ldn	ISDN local directory number. You can optionally specify second and third LDNs.

Default

A default SPID number and ISDN local directory numbers are not defined.

Command Mode

Interface configuration

Usage Guidelines

This command applies only to North America. If you want the SPID to be automatically detected, specify 0 for the spid-number variable.

Example

The following example specifies that the SPID should be automatically detected, that the primary ISDN local directory number is 4085551111, and that the secondary number is 4085552222:

router (config-if)# isdn spid2 0 4085551111 4085552222

Usage Guidelines

Use this command if your ISDN line is connected to a NI1 or a Nortel DMS-100 Custom switch. Your telephone service provider should issue an ISDN transfer code when you order call transferring.

Example

The following example specifies 62 as the ISDN transfer code:

router (config-if)# isdn transfer-code 62

isdn voice-priority

Use the isdn voice-priority interface configuration command to control the priority of data and voice calls for the telephones, fax machines, and modems connected to the router telephone ports. 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 according to the setting of this command. Use the no form of this command to disable a specified ISDN voice priority setting and to use the default setting.

isdn voice-priority local-directory-number {in | out} {always | conditional | off}
no isdn voice-priority local-directory-number

Syntax Description

local-directory-number	Local ISDN directory number assigned by your telephone service provider.
in	Incoming voice call.
out	Outgoing voice call.
always	Always bump a data call for a voice call.
conditional	Bump a data call only if there is more than one call to the same destination.
off	Never bump a data call for a voice call.

Default

A data call is always bumped for an incoming or outgoing voice call.

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 555-1111 in off

router (config-if)# isdn voice-priority 555-1111 out off

Table 2 Show Pots Status Field Descriptions

Field	Descriptions
POTS Global Configuration	Displays the settings of the telephone port physical characteristic commands. Also displays the following: •TX GAIN—Current transmit gain of telephone ports. •RX LOSS—Current transmit loss of telephone ports. •Filter Mask—Value determines which filters are currently enabled or disabled in the telephone port hardware. •Adaptive Cntrl Mask—Value determines if telephone port adaptive line impedance hardware is enabled or disabled.
Hook Switch Finite State Machine	Device driver that tracks state of telephone port hook switch.
CODEC Finite State Machine	Device driver that controls telephone port CODEC hardware.
CODEC Registers	Register contents of telephone port CODEC hardware.
CODEC Coefficients	CODEC coefficients selected by telephone port driver. Selected line type determines CODEC coefficients.
CSM Finite State Machine	State of call-switching module software (CSM).
Time Slot Control	Register that determines if telephone port voice or data packets are transmitted to an ISDN B channel.

Debug Command

This section documents the new debug pots command. The Cisco IOS Release 12.0 debug command references document all other debug commands used with this feature.

debug pots

Use the debug pots privileged EXEC command to display information on the telephone interfaces. Use the no form of this command to disable debugging output.

debug pots {driver | csm} [1 | 2]
no debug pots {driver | csm} [1 | 2]

Syntax Description

driver	Display driver debug information.
csm	Display CSM debug information.
1	(Optional) Display information for telephone port 1 only.
2	(Optional) Display information for telephone port 2 only.

Command Mode

Privileged EXEC

Usage Guidelines

The debug pots command displays driver and CSM debug information for telephone ports 1 and 2.

Sample Displays

The following is sample display from the debug pots driver 1 command. This sample display indicates that the telephone port driver is not receiving caller ID information from the ISDN line. Therefore, the analog caller ID device attached to the telephone port does not display caller ID information.
