CT1/CE1 Trunk Card
The Cisco AS5800 universal access server is equipped with modem cards for converting analog pulse code modulation (PCM) bitstreams to digital data. This chapter provides an overview of the 324 universal port card (CT1/CE1 trunk card), which supports modem services, and also includes steps for configuring your software and verifying and troubleshooting your CT1/CE1 trunk card installation. See Chapter 4 for information on the DMM modem card.
CT1/CE1 Trunk Card Overview
A universal port is a port that can carry the equivalent of one DS0 of network traffic. Network traffic can be a modem or fax connection.
Note
The 324 Universal Port Card supports data only when installed in the Cisco AS5800. Voice support is also available when the 324 UPC is installed in the Cisco AS5850.
The 324 universal port card uses NextPort hardware and firmware to provide universal ports for the Cisco AS5800 (thus the UPC is sometimes referred to as a NextPort module). These ports are grouped into SPEs. An SPE is a service processing element, supporting six universal ports. There are 54 SPEs per CT1/CE1 trunk card, for a total of 324 ports per CT1/CE1 trunk card. Each CT1/CE1 trunk card also has a minimum of a 64-MB SDRAM card. Configuration, management, and troubleshooting of universal ports can be done at the CT1/CE1 trunk card, SPE, and port level.
The Cisco AS5800 can be equipped with a maximum of seven CT1/CE1 trunk cards with upgradable firmware. Currently the CT1/CE1 trunk card supports data traffic, and is universal port capable, depending on the software and platform. Each CT1/CE1 trunk card plugs directly into the dial shelf backplane and has no external connections. Each CT1/CE1 trunk card has three LEDs, which indicate card status.
The Cisco AS5800 is capable of terminating as many as 2,048 port connections (slightly more than an OC-3) when equipped with seven CT1/CE1 trunk cards and three CT3 trunk cards. A split shelf configuration with a second router shelf, and second dial shelf controller are required to achieve full capacity. For details on configuring a Cisco AS5800 for maximum capacity, refer to the "Configuring Split Dial Shelves" section. A single router and a standard configuration supports as many as 1,344 port connections. Cisco IOS Release 12.1(2)XD is required for the CT1/CE1 trunk card. Unless your system has shipped with UPCs installed, you need to upgrade the Cisco IOS image on the dial shelf and router shelf or shelves.
Figure 6-1 shows the CT1/CE1 trunk card components.
Figure 6-1 CT1/CE1 Trunk Card Components
The CT1/CE1 trunk card performs the following functions:
•
•
•
•
You can install a CT1/CE1 trunk card in the slots numbered 2 to 11 on the dial shelf. If installed in slots 0 or 1 the CT1/CE1 trunk card is automatically powered down. We recommend that you install mixes of T3 and T1 cards, or E1 trunk cards in slots 2 to 5. Trunk cards are required for call termination and can only operate in slots 0 to 5. You can use double-density modem cards, CT1/CE1 trunk cards, and VoIP cards simultaneously.
LED Indicators
The CT1/CE1 trunk card has three LEDs (see Figure 6-2) to indicate card status. These LEDs can be green, yellow, or OFF.
Figure 6-2 CT1/CE1 Trunk Card Front Panel LEDs
During normal operation, all three LEDs light as described in Table 6-1.
Table 6-1 CT1/CE1 Trunk Card LED Descriptions
CPU/POWER
Green
CT1/CE1 trunk card passed diagnostics and the card CPU is operating properly.
Yellow
Lights shortly after the card is powered ON1 . Card CPU diagnostics start when the card starts receiving power, and the LED remains yellow while the diagnostics run.
OFF
UPC not receiving power, or portware failed to load. If the portware fails to load onto the card, the Cisco AS5800 will attempt to reload the portware automatically. If a programmed number of attempts to reload the portware fails, the Cisco AS5800 will power OFF the CT1/CE1 trunk card.
CALLS/MAINT
Green
The LED lights when at least one active call is switched through the card.
Yellow
Indicates card OIR status. The LED is yellow when the card has been busied out and has no calls, and may be removed without interrupting service.
OFF
The CALLS/MAINT LED is not lit if there is no traffic on the card and the card has not been busied out.
PORT STATUS
Green
Lights when all SPE modules have passed diagnostics and are operating properly.
OFF
LED remains OFF until diagnostics are complete. If this LED stays OFF, one or more SPE modules are missing from the card, or one or more SPEs failed diagnostics.
1 There is a slight delay from the time that power is applied to the card and the time that this LED lights.
SPE Firmware
SPE firmware is automatically downloaded to a CT1/CE1 trunk card from the dial shelf Cisco IOS image when you boot the system for the first time, or when you insert a CT1/CE1 trunk card while the system is operating. When you insert a CT1/CE1 trunk card while the system is operating, the Cisco IOS image recognizes the card and the dial shelf downloads the required portware to the cards. Cisco IOS Release 12.1(2)XD is required for the CT1/CE1 trunk card.
The SPE firmware image (also known as portware) is bundled with the Cisco IOS CT1/CE1 trunk card image. The SPE firmware image uses an auto detect mechanism, which enables the CT1/CE1 trunk card to service multiple call types. An SPE detects the call type and automatically configures itself for that operation. You can upgrade the firmware without upgrading Cisco IOS software, and different firmware versions can be configured to run on SPEs in the same UPC.
The SPEs can be programmed to collect ANI (calling number) and DNIS (called number) digits for caller identification information when the trunk cards are configured in channel associated signaling (CAS) mode. The SPE passes the ANI/DNIS information to the CT1/CE1 trunk card software with a portware mailbox message.
The CT1/CE1 trunk card supports the modem standards and features listed in Table 6-2.
Verifying and Troubleshooting the Installation
Cisco IOS Release 12.1(2)XD is required for the CT1/CE1 trunk card. The LEDs will not function without the proper Cisco IOS image running on the dial shelf. If you need to upgrade your Cisco IOS image, refer to Managing and Troubleshooting NextPort Services on the UPC, at:
http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5800/58featur/58nextpt.htm.
During normal operation, all three CT1/CE1 trunk card LEDs light when the CT1/CE1 trunk card is powered ON. When the CT1/CE1 trunk card CPU software starts running, it shuts OFF all LEDs except the power LED. The LEDs then light again as described in Table 6-1.
To complete the installation, verify that the CT1/CE1 trunk card LEDs operate properly by observing the following LED states:
•
If the CPU/POWER LED remains OFF, verify that the card is seated properly.
Note
If the CPU/POWER LED is yellow, diagnostics are still running on the CT1/CE1 trunk card. If the CPU/POWER LED stays yellow, contact CCO. To contact the Cisco Technical Assistance Center (TAC) refer to the "Obtaining Technical Assistance" section on page xv.
If the power LED lights on other CT1/CE1 trunk card s in the dial shelf, try inserting the CT1/CE1 trunk card in a different slot. If none of the power LEDs light, check your dial shelf power connections, power entry modules, and AC-input power supplies (if present).
•
If the CALLS/MAINT LED is OFF but the power LED is ON, there is no traffic on the card.
Verify that the other cards in the dial shelf work correctly. Verify that the card is seated properly. Try inserting the card in a different slot. Verify that you are using the correct portware using the show spe version command.
•
If the PORT STATUS LED is green, all SPEs present on the card pass diagnostics. You can also verify SPE operation by using the show spe command.
If the PORT STATUS LED is OFF, one or more SPEs present on the card have failed diagnostics.
If troubleshooting reveals problems with the CT1/CE1 trunk card, arrange to replace the CT1/CE1 trunk card. To contact the Cisco Technical Assistance Center (TAC) refer to the "Obtaining Technical Assistance" section on page xv.
Show Modem/Show SPE
Note
To verify proper function of a CT1/CE1 trunk card in a Cisco AS5800, you must use the show spe command and its variants described in Managing and Troubleshooting NextPort Services on the UPC, available online at:
http://www.cisco.com/univercd/td/doc/product/access/acs_serv/as5800/58featur/58nextpt.htm.
For further troubleshooting information, refer to the Cisco AS5800 Universal Access Server Hardware Installation Guide.
Configuring the Ports
Timesaver
Note
If you are replacing a dial shelf card with a new dial shelf card of the same type in the same slot, the system software recognizes the new dial shelf card interfaces and brings them up automatically. No additional configuration is needed.
You must insert the UPC in the desired slot as described in Chapter 1, "Replacing or Installing Dial Shelf Cards."
Before you configure your access server to use UPCs, load the proper Cisco IOS images on both the router shelf or shelves, and the dial shelf.
Table 6-3 contains sample commands to help you configure your CT1/CE1 trunk card for basic dialup service.
Tips
If you are installing a new CT1/CE1 trunk card into the dial shelf, no additional configuration is needed. For additional system software configuration information, refer to the Cisco AS5800 Universal Access Server Operation, Administration, Maintenance, and Provisioning Guide.
Configuring Split Dial Shelves
To achieve the maximum capacity of 2048 port connections using seven CT1/CE1 trunk cards and three T3 plus one T1 trunks requires a split dial shelf configuration using two router shelves. A new configuration command is available to define the split point: dial-shelf split backplane-ds0 option.
The options for this command come in pairs, varying according to the desired configuration. You need to log in to each router shelf and separately configure the routers for their intended load. In most circumstances Cisco recommends that you select the predefined options. These options are designed to be matched pairs as seen in Table 6-4.

1 This option is used to revert to the default for an environment using 6 E1 lines.
The dial-shelf split slot 0 3 4 5 command must be defined and used for the dial-shelf split backplane-ds0 option command to be available. You can also select the user defined option to define your own split.
Even if your system is already using a split dial shelf configuration, configuring one router shelf to handle two T3 trunks and the other router to handle the third trunk requires that you take the entire access server out of service. Busyout all connections before attempting to reconfigure. The configuration must be changed to setup one pool of TDM resources that can be used by either DMM cards or UPCs, and a second pool of two streams that contains TDM resources that can only be used by UPCs.
If you have more trunk capacity than 2048 calls, it is your decision how to provision the trunks so that the backplane capacity is not exceeded. If more calls come in than backplane DS0 capacity for that half of the split, the call is rejected and an error message is printed for each call. This cannot be detected while a new configuration is being built because the router cannot tell which T1 trunks are provisioned and which are not. You might want some trunks in hot standby.
The DMM, HMM, and VoIP cards can only use 1792 DS0 of the available 2048 backplane DS0. The UPC and trunk cards can use the full 2048 backplane DS0. The show tdm splitbackplane command will show the resources in two groups, the first 1792 accessible to all cards, and the remaining 256 accessible only to UPC and trunk cards.
Configuration Scenarios
The following configuration scenarios apply for environments using T3 CAS, T3 PRI, and E1 PRI:
T3 CAS
Option 1: Straight three T3 environment—two T3/ one T3 split
Router shelf 1, two T3s—dial-shelf backplane-ds0 2ct3cas
Router shelf 2, one T3—dial-shelf backplane-ds0 1ct3cas
This setting combination provides 1344 DS0s (four or five UPCs) to one router shelf and 672 DS0s (two or three UPCs) to the other for a total of 2016 possible analog calls terminated. This leaves 276 spare ports on the router shelf 1 side, and a shortage of 24 ports on the router shelf 2 side. One DMM card could be used to provide an additional 24 ports and spares for the router shelf 2 of the split.
Option 2: 3 T3—with 1 T3 demuxed into T1s plus an extra 1 T1 service in addition to the 3 T3s
Router shelf 1, one T3 plus two T1s—dial-shelf backplane-ds0 part2ct1ct3cas
Router shelf 2, one T3 plus one T1—dial-shelf backplane-ds0 part1ct1ct3cas
This setting combination provides 1152 DS0s (four UPCs) to one router shelf and 888 DS0s (three UPCs) to the other for a total of 2040 possible analog calls terminated. This leaves 144 spare ports on the router shelf 1 side, and 84 spare ports on the router shelf 2 side. This leaves one empty slot, but does not require any DMMs to be added. The router shelf load in this configuration is more even than in option 1.
T3 PRI
Option 3: 3 CT3 environment—Straight two CT3/one CT3 split
Router shelf 1, two T3s—dial-shelf backplane-ds0 2ct3isdn
Router shelf 2, one T3—dial-shelf backplane-ds0 part1ct1ct3isdn_b
This setting combination provides 1288 DS0s (four UPCs) to one router shelf and 644 DS0s (two UPCs) to the other for a total of 1932 analog calls terminated. This leaves only eight spare ports on the router shelf 1 side, and four spare ports on the router shelf 2 side. This also leaves three empty slots so one DMM per side can be added to provide spare modems if required. The router shelf load in this configuration is somewhat uneven: one router shelf is heavily loaded, the other is at half capacity.
Option 4: 3 CT3 environment—with a MUX to split 1 CT3 into CT1s PLUS an extra 5 CT1 services in addition to the 3 CT3s
Router shelf 1, one T3 plus two T1s—dial-shelf backplane-ds0 part2ct1ct3isdn
Router shelf 2, one T3 plus one T1—dial-shelf backplane-ds0 part1ct1ct3isdn
This setting combination provides 1150 DS0s (four UPCs) to one router shelf and 897 DS0s (three UPCs) to the other for a total of 2047 analog calls terminated. This leaves 146 spare ports on the router shelf 1 side, and 75 spare ports on the router shelf 2 side. This leaves one empty slot, but does not require any DMMs to be added. The router shelf load in this configuration is more even than in option 1.
E1-PRI
Option 5: 6 E1-PRI environment
Router shelf 1, three E1s— 3ce1
Router shelf 2, three E1s—3ce1
This setting combination provides 960 DS0s (three UPCs) to one router shelf and 960 DS0s (three UPCs) to the other for a total of 1920 possible analog calls terminated. This leaves 12 spare ports on the router shelf 1 side, and 12 spare ports on the router shelf 2 side. This leaves no empty slots, but does not require any DMMs to be added. The router shelf load in this configuration is evenly split.
