Hi, Is there any show/debug command to see whether the isdn link is point-to-point or multipoint?

When you configure isdn static tei, it's p-to-p, else, its p-to-mp.

Multinumber BRi are p-to-mp, in fact see your above got assigned a dynamic TEI.

It will only be pt-pt, but you can have multiple calls into a hub depending on the ISDN presentation, ISDN 2 or ISDN PRI.

Check for no TEI assigned when configured p-to-mp on a p-t-p circuit.

Generally, multiple circuits with a single pilot number are p-t-p.

Hi,

we have ISDN2e. I want to check whether this ISDN is p-to-p or p-to-mp. From the configuration, i have not configured it manullay as a point to point or point to multipoint.

On this ISDN we have two ISDN numbers. How can i check it? below is the show isdn status command.

show isdn status

Global ISDN Switchtype = basic-net3

ISDN BRI0 interface

dsl 0, interface ISDN Switchtype = basic-net3

Layer 1 Status:

ACTIVE

Layer 2 Status:

TEI = 115, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED

Layer 3 Status:

0 Active Layer 3 Call(s)

Active dsl 0 CCBs = 0

The Free Channel Mask: 0x80000003

Total Allocated ISDN CCBs = 0

Hi,

Pls tell me if that BRI configured as Point to point then what will be a value for the TEI

Check your dialer map statements.

The TEI (Terminal Ennpoint Identifier) is assigned to the line from the exchange.

Always 0.
