Cisco IOS Release 12.0(3)T for Cisco 800 Series Routers

Feature Summary

Cisco IOS Release 12.0(3)T provides software support for the Cisco 800 series routers. This document describes how to set up the automatic detection of Integrated Services Digital Network (ISDN) service profile identifiers (SPIDs) and switch type (for North America only); how to verify your dial-on-demand routing (DDR) configuration; how to prioritize your data and voice calls; how to configure the physical characteristics of your telephone interface; how to create dial peers; how to activate three-way call conferencing; and how to activate call transferring.

Benefits

The Cisco 800 series routers connect small professional offices or telecommuters over ISDN Basic Rate Interface (BRI) lines to the Internet and corporate networks. The routers provide bridging and multiprotocol routing capability between LAN and WAN ports.

List of Terms

Dial peer—You can create a dial peer to determine how incoming calls are routed to the telephone ports. A dial peer also determines the calling party number for outgoing calls. A dial peer is composed of an identifying tag number, an ISDN directory number, and a telephone port number. A dial peer can also include commands to disable call waiting and to set up a distinctive ring.

ISDN directory number—The local 10-digit ISDN telephone number (including area code) of your router, such as 408-555-1111.

Telephone interface—A logical interface that you must configure to make an analog telephone, fax machine, or modem connected to a telephone port work properly.

Telephone port—The physical telephone port on the router back panel.

Platforms

Cisco IOS Release 12.0(3)T is supported on these platforms:

•Cisco 801 router

•Cisco 802 router

•Cisco 803 router

•Cisco 804 router

Supported MIBs and RFCs

None.

Configuration Tasks

This section describes the following Cisco 800 series configuration tasks:

•Setting up the automatic detection of ISDN SPIDs and switch type (North America only)

•Verifying your DDR configuration

•Prioritizing data and voice calls

•Configuring the physical characteristics of your telephone interface

•Creating a dial peer

•Activating three-way call conferencing

Step 4

Enable the automatic detection of ISDN SPIDs and switch type.

isdn autodetect

Step 5

Exit the ISDN interface configuration mode, and return to privileged EXEC mode.

end

When entering the isdn spid1 and isdn spid2 commands, you can specify 0 for the spid-number argument to indicate that the SPID is automatically detected.

Verifying DDR Configuration

You can verify your DDR configuration by making an ISDN data call from the command-line interface (CLI). Enter the following commands from privileged EXEC mode.

Task

Command

Step 1

Initiate the data call.

isdn call interface interface dialing-string [speed 56 | 64]

Step 2

Disconnect the data call without bringing down the ISDN interface.

isdn disconnect interface bri 0 {b1 | b2 | all}

Prioritizing Data and Voice Calls

By default, the router always bumps a data call for a voice call. You can reconfigure the priority of data and voice calls for telephones, fax machines, or modems connected to the router telephone ports.

Task

Command

Step 1

Enter configuration mode.

configure terminal

Step 2

Enter configuration mode for the ISDN interface.

Step 4

Exit the ISDN interface configuration mode, and return to privileged EXEC mode.

end

If you have multiple ISDN directory numbers associated with a SPID, then the outgoing voice priority that you set for any of these directory numbers applies to the other numbers.

The setting of the pots dialing-method command affects when you hear a busy signal in the following situation:

•A data call cannot be bumped.

•You are trying to make an outgoing call.

If the setting is overlap, you hear a busy signal when you pick up the handset. If the setting is enblock, you initially hear a dial tone and then a busy signal.

Configuration Examples

This section provides examples of the following Cisco 800 series configuration tasks:

•Setting up the automatic detection of ISDN SPIDs and switch type (North America only)

•Verifying your DDR configuration

•Prioritizing data and voice calls

•Configuring the physical characteristics of your telephone interface

•Creating dial peers

•Activating three-way call conferencing

•Activating call transferring

Setting Up Automatic Detection of ISDN SPIDs and Switch Type

To set up the automatic detection of ISDN SPIDs and switch type, follow these steps. These steps apply to North America only.

Step 1 Associate the ISDN LDNs provided by your telephone service provider to the first and second SPIDs:

isdn spid1 spid-number ldn [ldn] [ldn]

isdn spid2 spid-number ldn [ldn] [ldn]

Because the SPID numbers provided by your telephone service provider are automatically detected, you do not need to specify them in this command; instead, you can specify 0 to indicate that the SPID numbers should be automatically detected.

For example, if your telephone service provider assigned 408-555-1111 as a primary directory number and 408-555-2222 as a secondary directory number for the first SPID and 408-555-3333 and 408-555-4444 for the second SPID, you can enter the following commands:
router (config-if)# isdn spid1 0 4085551111 4085552222
router (config-if)# isdn spid2 0 4085553333 4085554444
Always provide the complete directory number, including the area code.

Step 2 Enable the automatic detection of ISDN SPID numbers and switch type:
router (config-if)# isdn autodetect
Verifying DDR Configuration

You can test your DDR configuration by making an ISDN data call through the CLI:

Step 1 Initiate the data call:

isdn call interface interface dialing-string [speed 56 | 64]

For example, enter the following command to initiate the call through the BRI to 555-1111 at the line speed of 56 kbps:
router# isdn call interface bri 0 5551111 speed 56
Step 2 Disconnect the data call without bringing down the interface:

isdn disconnect interface interface {b1 | b2 | all}

For example, enter the following command to disconnect the data call on B channel 1 of the BRI:
router# isdn disconnect interface bri 0 b1
Prioritizing Data and Voice Calls

To control the priority of data and voice calls for telephones, fax machines, and modems connected to a router telephone port, enter the following command:

isdn voice-priority local-directory-number {in | out} {always | conditional | off}

The following is a sample voice priority configuration:
router (config-if)# isdn voice-priority 5551111 in conditional
router (config-if)# isdn voice-priority 5551111 out conditional
router (config-if)# isdn voice-priority 5552222 in off
router (config-if)# isdn voice-priority 5552222 out off
In this example, if an ISDN circuit endpoint is busy with a data call or calls and either a voice call comes in (incoming) or you attempt to place a voice call (outgoing), the data call is handled in the following ways:

•For 555-1111, the data call is bumped.

•For 555-2222, the data call is not bumped. The voice call receives a busy signal.

Configuring Telephone Interface Physical Characteristics

To configure the telephone interface physical characteristics, follow these steps:

Step 1 Specify the country where your router is located:

pots country country

Enter the pots country ? command to get a list of supported countries and the code you must input to indicate a particular country. For example, if your router is located in Germany, enter the following command:
router (config)# pots country de
This command determines the physical characteristics of the telephone interfaces. By specifying Germany, you are configuring your telephone to use Germany-specific default settings for each of the physical characteristics.

Step 2 Exit to privileged EXEC mode:
router (config)# exit
Step 3 Display the setting of each physical characteristic:
router # show pots status
The following sample output shows German-specific default settings for each physical characteristic. (The show pots status command typically displays telephone interface physical characteristics and status of telephone ports 1 and 2. This sample output is truncated to display only the physical characteristics.)
POTS Global Configuration:
   Country: Germany
   Dialing Method: Overlap, Tone Source: Remote, CallerId Support: NO
   Line Type: Complex Impedance, PCM Encoding: a-law, Disc Type: OSI,
   Ringing Frequency: 20Hz, Distinctive Ring Guard timer: 0 msec
   Disconnect timer: 1000 msec, Disconnect Silence timer: 5 sec
	...
Step 4 After viewing the default settings for the physical characteristics, determine if you need to change any settings.

Step 5 If necessary, change any country-specific default settings.

For a summary of the physical characteristics commands, refer to the "Configuring Telephone Interface Physical Characteristics" section. For example, to change the dialing method from overlap to enblock, do the following:

(a) Enter configuration mode:
router # configure terminal
(b) Enter the following command:
router (config)# pots dialing-method enblock
Creating a Dial Peer

You can create a dial peer to determine how incoming calls are routed to the telephone ports. For example, if you have connected one voice device (555-1111) to port 1 and another (555-2222) to port 2, you can create two dial peers:
dial-peer voice 1 pots  
destination-pattern 5551111 
port 1 
no call-waiting 
ring 0
dial-peer voice 2 pots  
destination-pattern 5552222 
port 2 
no call-waiting 
ring 0
When a caller dials 555-1111, the call is routed to port 1. When a caller dials 555-2222, the call is routed to port 2. If the dial peers are not created, calls to both numbers are routed to port 1.

After creating the dial peers, enter the isdn incoming-voice modem command to ensure that the incoming ISDN voice calls are forwarded to the telephone ports.

Activating Three-Way Call Conferencing

To activate three-way call conferencing, enter the following command:

isdn conference-code range

For example, if your telephone service provider supplies 61 as the conference code, enter the following command:
router (config-if)# isdn conference-code 61
Activating Call Transferring

To activate call transferring, enter the following command:

isdn transfer-code range

For example, if your telephone service provider supplies 62 as the transfer code, enter the following command:
router (config-if)# isdn transfer-code 62

Command Mode

Interface configuration

Usage Guidelines

If you are in North America and have multiple ISDN directory numbers associated with a SPID, the outgoing voice priority that you set for any of these directory numbers applies to the other directory numbers. For example, if you enter the following commands, the outgoing voice priority for all directory numbers specified in the isdn spid1 command is set to conditional:
router (config-if)# isdn spid1 0 4085551111 4085552222 4085553333
router (config-if)# isdn voice-priority 5551111 out conditional
The setting of the pots dialing-method command affects when you hear a busy signal in the following situation:

•A data call cannot be bumped.

•You are trying to make an outgoing call.

If the setting is overlap, you hear a busy signal when you pick up the handset. If the setting is enblock, you initially hear a dial tone and then a busy signal.

Example

The following example specifies that a data call for the specified ISDN directory number never be bumped for an incoming or an outgoing voice call:
router (config-if)# isdn voice-priority 5551111 in off
router (config-if)# isdn voice-priority 5551111 out off
