CLI Procedure for Configuring ISDN Services

Note: This procedure assumes you have installed the ISDN module in the Passport 4400.

Display the IfIndexes for ISDN.

CLI> show system IfIndex operational

A table similar to the following appears:

IfIndex	IfExtType	PPA	IfSlot
1	ethernetCsmacd	0	base
2	propVirtual	0	base
3	other	0	base
4	propVirtual	1	base
5	isdns	2	base
6	ds0	2	base
7	ds0	2	base
8	lapd	2	base
9	isdn	2	base
150	propMultiplexor	1	base
151	other	1	base
153	propMultiplexor	2	base
154	other	2	base
156	propMultiplexor	3	base
157	other	3	base

Note: For Passport 4430, 4450, and 4455, the Logical Interface Module (LIM) name for the base module is always limA. The WAN and Expansion modules are numbered lim1 through lim4. For the Passport 4460, the LIM name for the base module is always base, Expansion modules are named exp1, exp2, and the PCMCIA module is named pcmciaExp.

The following WAN interface extension types relate to ISDN:

isdns (5)	The physical interface type (S/T) of the ISDN circuit card; isdnu would designate a U-type circuit card. Take note of this IfIndex; ISDN configuring procedures may require this IfIndex number to identify the ISDN BRI service.
ds0 (6,7)	B-channel 1 or B-channel 2 of the ISDN BRI service. Each ISDN B-channel is represented by an IfIndex, even though the Passport 4400 currently supports only one B-channel.
lapd (8)	The ISDN D-channel data link layer (LAPD) interface.
isdn (9)	The signalling D-channel for the ISDN service.
propMultiplexor (153)	The physical port interface of the ISDN module. Note the third column (PPA) in the above display, which indicates the physical port (2).

The following command displays all currently configured ISDN peer entries. Note that it is possible to have more than one service configured for a physical ISDN interface.

CLI> show isdn dialControl basePeer table

Id	IfIndex	BChannel
1	5	1
3	5	1

If there is an ISDN entry already configured for the interface in question, the ISDN parameters may be modified through the use of the define isdn commands. See Optional ISDN Parameters for a list of parameters that may be modified.

Add a new ISDN peer entry.

CLI> add isdn peer

Parameter	Range of Values	Required Actions
<Id>	INTEGER (1..2147483647)	Assign a unique ID number for this ISDN service. Consult the show isdn dialControl basePeer table display above, and select an ID number that is not in use.
<IfIndex>	INTEGER (1..255)	Enter the IfIndex that corresponds to isdns or isdnu from the show system IfIndex configured table in Step 1.
<BChannel>	INTEGER (0..32)	For 128 kb/s leased lines, set this variable to 1.
<OrigniateAddress>	"String" (0..131)	Enter the destination telephone number in " " (quotes).
<SubAddress>	"String" (0..131)	Enter the subaddress of the destination telephone number in " " (quotes).

Note: It is recommended that the new ID number be higher than the existing ID numbers. For example, in the above display (show isdn dialControl basePeer table), IDs 1 and 3 are in use, so use the number 4 for this ISDN service.

Example:

CLI> add isdn peer 4 5 1 "5551234" "789"

Save the current configuration and reset the Passport 4400.

CLI> save configuration update

CLI> reset system current reset
