Feature Information for T1/E1 Mode for SHDSL
T1/E1 Mode for SHDSL
This document describes the T1/E1 Mode for SHDSL feature for the Cisco 1700 series, Cisco 2600 series, Cisco 3631, Cisco 3700, and Cisco 3800 series routers.
The T1/E1 Mode for SHDSL feature adds T1 and E1 support on the new single-port multiline G.SHDSL WAN interface card (WIC), or WIC-1SHDSL-V2, to build on the existing features of the Multirate Symmetrical High- Digital Subscriber Line (G.SHDSL) feature supported on the 1-port G.SHDSL WAN interface card. Two-Wire Mode over SHDSL incorporates the 2.x firmware version and the latest hybrid circuit from Globespan.
The T1/E1 Mode for SHDSL feature supports T1 and E1 in two-wire mode. Embedded Operations Channel (EOC) message support for customer premises equipment (CPE) is provided for two-wire CPE mode. Some central office (CO) messages are also supported when in two-wire CO mode.

•Minimum memory recommendations are shown in Table 30.
Restrictions for T1/E1 Mode for SHDSL
The following lists the restrictions for T1/E1 mode:
•The T1/E1 Mode for SHDSL feature is intended for use with the WIC-1SHDSL-V2. T1/E1 Mode is not supported on the WIC-1SHDSL.
•While this feature can work with earlier WICs, not all commands of this feature are supported in earlier WICs. If using a WIC other than WIC-1SHDSL-V2, refer to one of the following documents:
–The 1-Port G.SHDSL WAN Interface Card for Cisco 2600 Series and Cisco 3600 Series Routers feature module at:
http://www.cisco.com/en/US/docs/ios/12_2t/12_2t8/feature/guide/ft_gdsl8.html
–Installing the G.SHDSL ATM WIC on the Cisco 1700 Series Router at:
http://www.cisco.com/en/US/docs/routers/access/1700/software/feature/guide/GSHDSLup.html
•The WIC-1SHDSL-V2 should be inserted only into onboard WIC slots or NM-2W network modules. This WIC is not supported in combination network modules (NM-xFE2W and NM-xFE2W-V2).
•The T1/E1 Mode for SHDSL feature is frame-based (Time Division Multiplexing (TDM)) and therefore does not support ATM features. For example, T1/E1 Mode for SHDSL feature does not support ATM adaption layer 1 (AAL1) and/or circuit emulation service.
•T1/E1 Mode for SHDSL feature is not supported in four-wire mode.
•TDM cross-connects are only supported between WIC slots on NM-2W network modules.

SHDSL Features
Supported SHDSL features are listed as follows:
•ITU G.991.2 support (full support for Annex A & B)
–Dying Gasp (ITU G.991.2) is supported.
–Terminating wetting current is supported.
–T1/E1 mode when in two-wire configuration is supported.
•ITU G.991.2 support (partial support for Annex E)
–E.4—Aligned DS1/fractional DS1 support for T1.
–E.7—Aligned DS1/fractional DS1 support for E1.
–E.9—ATM transport.
Interface and Controller Numbering on the Cisco 1721 Router
If a WIC-1SHDSL-V2 is installed in a Cisco 1721 router, the interfaces and controllers are assigned numbers based on a numbering scheme that is different from the slot numbering system on other Cisco routers. This is because the Cisco 1721 router assigns only a slot number without also assigning a port number. Other Cisco routers typically use a slot and port number combination.
If the WIC-1SHDSL-V2 is installed in slot 0, the T1/E1 controllers and the ATM interfaces (ADSL or SHDSL) will be numbered relative to the WIC-1SHDSL-V2 (as the DSL controller) in slot 0. See Table 31 for examples of the slot numbering scheme on the Cisco 1721.
With an ATM or MFT T1/E1 card in slot 0, the WIC-1SHDSL-V2 in slot 1 will be numbered relative to the number of ports in slot 0.
If both slots are occupied by the WIC-1SHDSL-V2 as DSL controllers, the logical interfaces configured on each controller will have the same number as the slot number occupied by the DSL controller. All logical interfaces on the WIC-1SHDSL-V2, such as serial interfaces created during the configuration of channel groups in T1/E1 mode, will have the same number as the DSL controller.
Interface Numbering on Cisco 2800 Series and Cisco 3800 Series Routers
This section describes the interface numbering scheme for Cisco 2800 and Cisco 3800 series routers. If an interface card is installed in a Cisco 2800 series or Cisco 3800 series router, the interfaces must use a triple-number scheme to identify them. This triple-number assignment is different from the standard interface numbering scheme on other Cisco routers.
Table 32 shows the interface numbering for the onboard Fast Ethernet ports and the interface slots on Cisco 2800 and Cisco 3800 series routers.

1. no mode
2. mode {t1 | e1}
3. controller {t1 | e1} slot/port
4. clock source {internal | line}
DETAILED STEPS
Command or Action PurposeStep 1
no mode
Example:Router(config-controller)# no mode
Clears any current logical controller.
Step 2
mode {t1 | e1}
Example:Router(config-controller)# mode e1
Creates a logical T1 or E1 controller.
•t1 | e1—The type of controller.
Step 3
controller {t1 | e1} slot/port
Example:Router(config-controller)# controller e1 0/1
Enters controller configuration mode and configures the logical T1/E1 controller created in Step 2.
The keywords and arguments are as follows:
•{t1|e1}—The type of controller.
•slot/port—The backplane slot number and port number for the interface being configured.
Step 4
clock source {internal | line}
Example:Router(config-controller)# clock source internal
Configures the clock source on the router:
•internal—Configures the clock to derive its source internally. Use this on the CO controller.
•line—Configures the clock to derive its source from the CO side of the line. Use this on the CPE controller.
Note This command only works when using an NM-2W network module. If the WIC is in a slot of the Cisco 2600 router, this command does not apply.
Note This command works only when using a non-voice (data) image on the Cisco 1700 series routers. For IP voice images, use the tdm clock command instead (see the "Configuring the TDM Clock" section).
What to Do Next
Verify the configuration using the detailed steps in"Verifying Two-Wire CPE T1/E1 Configuration Status" section
Configuring the TDM Clock

Figure 30 Typical PBX Voice TDM Traffic Setup
In this example, a WIC-1SHDSL-V2 is used on both sides to link the Cisco 2620XM and the Cisco 2651XM by using one pair of copper wire, as shown in Figure 30. The two WICs are configured into T1 mode.
Under newly created logical T1 controller at the Cisco 2620XM router, ten TDM groups are allocated to deliver TDM voice traffic from the PBX. The TDM voice traffic from the PBX passes first into the VWIC-2MFT-T1 at the Cisco 2620 router, where the voice traffic is switched onto the WIC-1SHDSL-V2 and in turn is delivered over SHDSL to the CO side, the Cisco 2651XM. At the Cisco 2651XM, the TDM voice traffic is switched and passed onto the TDM or PSTN network, which can be done through another VWIC-2MFT-T1 at the CO side.
In the same T1 logical Controllers on both CPE and CO sides, the left time slots are allocated to channel-groups. The created channel-groups are used to make serial interfaces at both CPE and CO sides. The logical serial interfaces can be used to deliver any IP traffic; for example, the PC can communicate to file server on the remote CO side.
The following sample configurations are given for reference.

Glossary
ABR—available bit rate. An ATM service type in which the ATM network makes a "best effort" to meet the transmitter's bandwidth requirements. ABR uses a congestion feedback mechanism that allows the ATM network to notify the transmitters that they should reduce their rate of data transmission until the congestion decreases. Thus, ABR offers a qualitative guarantee that the transmitter's data can get to the intended receivers without unwanted cell loss.
CO—central office. Local telephone company office to which all local loops in a given area connect and in which circuit switching of subscriber lines occur.
CPE—customer premises equipment. CPE includes devices such as CSU/DSUs, modems, and ISDN terminal adapters, required to provide an electromagnetic termination for wide-area network circuits before connecting to the router or access server. This equipment was historically provided by the telephone company, but is now typically provided by the customer in North American markets.
DMT—Discrete Multi-Tone is the ANSI-specified modulation technique for G.SHDSL (ANSI-T1.413). DMT is theoretically capable of more speed than CAP. The key providers of DMT are Alcatel, Amati, Aware/ADI, and Orckit.
Downstream—Refers to the transmission of data from the central office (CO or COE) to the customer premises equipment (CPE).
G.SHDSL—Multirate Symmetrical High-Speed Digital Subscriber Line.
UBR—unspecified bit rate. QoS class defined by the ATM Forum for ATM networks. UBR allows any amount of data up to a specified maximum to be sent across the network, but there are no guarantees in terms of cell loss rate and delay. Compare with ABR (available bit rate), CBR, and VBR.
Upstream—Refers to the transmission of data from the customer premise equipment (CPE) to the central office equipment (CO or COE).
VBR—variable bit rate. QoS class defined by the ATM Forum for ATM networks. VBR is subdivided into a real time (rt) class and non-real time (nrt) class.
VBR-rt—VBR-real time is used for connections in which there is a fixed timing relationship between samples.
VBR-nrt—VBR-non-real time is used for connections in which there is no fixed timing relationship between samples, but that still need a guaranteed QoS. Compare with ABR (available bit rate), CBR, and UBR.
VDSL—very high-speed digital subscriber line. This is a high-speed asymmetrical service in the 10 to 25-Mbps range and is typically limited to less than 5000 feet. The targeted application for this technology is a hybrid fiber copper system (fiber to the neighborhood).
