The default value of the field changes depending upon which value the Interface

field contains.

!CAUTION:

It is critical that administration on this switch co rrectly pairs with the

administration of the far-end switch. If the far-end is administered as the b

side, this field should be set to a regardless of whether the layer 2

designation is peer-master or peer-slave, and vice versa.

Protocol Version

In countries whose public networks allow multiple layer 3 signaling protocols for

ISDN-PRI service, this field selects the protocol that matches your network

service provider’s protocol. Refer to ‘‘Public network signalin g adminis trat ion fo r

ISDN-PRI Layer 3’’ on page 1321 to see which countries support which

protocols.

This field appears only when:

■The Signaling Mode field is isdn-pri and the Connect field is network.

■The Signaling Mode field is isdn-pri, the Connect field is pbx, and the

Interface field is user or network.

!WARNING:

The AT&T Switched Network Protocol does not support restricted displays

of connected numbers. Therefore, if you administer th e 1a

country-protocol/protocol-version combination on the DS1 screen, you

cannot set the Send Connected Number field to

(restricted) on the

ISDN-PRI Trunk Group screen, as this causes display problems.

Valid entries Usage

aEnter a if the Interface field is peer-master (this

switch overrides the far-end when glare occurs).

bEnter b if the Interface field is peer-slave (this

switch releases the contested circuit and looks for

another when glare occurs).

Valid entries Usage

aThe entry in this field must match the protocol used by your

network service provider, so work with your vendor to

determine the appropriate entry.
