10.17 If a user attempts to place an outgoing call using an individual B-channel trunk, the sys-
tem sends a Setup Request to the network that requests that B-channel. If the network specifies
a different B-channel (possibly because of a glare condition), the system releases the call and
the user hears busy tone. The call camps on to the selected B-channel trunk. If the same situa-
tion occurs when the user selects a B-channel through a trunk group or ARS, the system simply
moves to the next available trunk instead of camping on.
10.18 The CO Hookflash (Recall) feature cannot be used on B-channel trunks.
10.19 The available ISDN services are shown in the chart below. They are divided into two
categories: services supported by the system and unsupported services. If the B-channel trunks
provide an unsupported service, the system still functions properly. However, it does not make
use of the service.
10.20 Primary Rate Call Type: All Primary rate ISDN calls have a specific number type
(International, National, Network, or Local/Subscriber) and numbering plan field (ISDN, Tele-
phony, or Private) indicated in the call setup message to the public network peer. In certain
cases, front end equipment interfacing with the ISDN user (CPE) peer requires a specific num-
ber type and/or numbering plan. The number type and numbering plan are programmable per
call type for each equipped primary rate card. The operation of this feature is transparent to the
user. After the number type and numbering plan are programmed, the Primary rate call setup
message includes this information for each call. To set the Primary Rate Call Type for a T1/E1
card, select System—Cabinets, then double-click on the card (or right-click and select Explore
Card). Then select
