Network Service 4
Use this procedure to specify the type of outgoing service provided by each
B-channel group.
NOTES:
1. You can enter a service not shown on the Network Service screen by
using the 5-digit binary code that represents the service in the Network
Facilities Information Element of ISDN PRI signaling protocol. For
information on these codes, contact your service provider. See
“Miscellaneous Procedure” included in this network service procedure.
2. In Release 6.0 and later systems, setting the switch type to Legend-PBX
or Legend-NTWK automatically assigns the B-channels for the specified
PRI tandem trunk to a single unused B-channel group. This group is
automatically assigned LEGEND UDP as the general type of network
service and Electronic Tandem Network (ETN) as specific LEGEND
UDP network service. As long as the switch type for the PRI trunk
remains as Legend-PBX or Legend-NTWK, you cannot change the type
of network service. For more information about switch types, see
“Switch Type” on page 4–166
