•
DS1 Circuit Pack — This screen is required if using ISDN-PRI interfaces.
— DS1 (T1) Circuit Pack
Assign all fields as required. For Facility Associated Signaling , up to 23 ports are
available for administration as trunk members in an associated ISDN-PRI trunk group.
The 24th port is used as a signaling channel. For
Non-Facility Associated Signaling , all
24 ports may be used on certain DS1 circuit packs. The D-channel signaling function for
these packs must be provided by a designated DS1 pack on its 24th channel.
— E1 Circuit Pack
Assign all fields as required. For Facility Associated Signaling , up to 30 ports are
available for administration as trunk members in an associated ISDN-PRI trunk group.
Port number 16 is used as a signaling channel.
•
Maintenance-Related System-Parameters — Use this screen only for a TN778. Set the
Packet
Bus Maint
field to y.
•
ISDN Trunk Group — Enter information in all the fields except the trunk group members. When
using ISDN-PRI interfaces, enter the members after you establish the signaling links.
•
Signaling Group — This screen is required if ISDN-PRI interfaces are used. Complete all fields.
This screen identifies groups of ISDN-PRI DS1 interface B-channels for which a given D-channel
(or D-channel pair) will carry the associated signaling information (supports the Facility and
Non-Facility Associated Signaling feature). Each DS1 board that is required to have a D-channel
must be in a different signaling group by itself (unless D-channel backup is needed, in which case
a second DS1 is administered as a backup D-channel). You are not required to select a channel for
a trunk group, but if you do, you must have already defined the trunk group as type ISDN.
NOTE:
The following three screens, Processor Interface Data Module, Communication
Interface Links, and Communication Processor Channel Assignment are used only to
support the ISDN-PRI interfaces using PI TN765.
•
Processor Interface Data Module — Use this screen only for a TN765. Assign up to 8 interface
links using 8 Processor Interface Data Module screens for multi-carrier cabinet systems, and up
to 4 links for single-carrier cabinet systems. One Processor Interface Data Module screen must
be completed for each interface link to be assigned.
•
Communication Interface Links — Use this screen only for a TN765. Assign link numbers 01 to
08 for a multi-carrier cabinet system or links 01 to 04 for a single-carrier cabinet system as
required. When first administering this screen for ISDN in Avaya Communication Manager, do
not administer the
Enable field.
•
Communication Processor Channel Assignment — Use this screen only for a TN765. Enter
assigned link numbers and assign associated channel numbers to each link. Complete all fields of
the screen as required. When first administering this screen for ISDN in Avaya Communication
Manager, you need to:
— First, administer the Interface Links screen, except the Enable field.
— Second, administer the
ISDN
fields on the Processor Channel screen.
— Last, go back to the Interface Links screen and administer the Enable field.
•
ISDN Numbering - Public/Unknown — Complete all fields. This screen supports the ISDN Call
Identification Display.
•
ISDN Numbering - Private — Complete all fields. This screen supports the ISDN Call
Identification Display.
