PKT-INT (Packet Interface)
The Packet Interface (PKT-INT) interfaces between the TN2402/TN798 Processor
circuit pack and packet endpoints (such as ISDN-BRI stations or ISDN-PRI
trunks). Two instances of PKT-INT are provided on the TN2402/TN798 Processor
circuit pack:
■
PKT-INT 1 (1A1) communicates through the TDM bus only. It provides
signaling for circuit packs that can receive signaling packets over the TDM
bus, e.g., the TN767E DS1 Interface circuit pack (for ISDN-PRI
applications) and the TN556C circuit pack (for ISDN-BRI applications).
■
PKT-INT 2 (1A2) communicates through the Packet bus only. It provides
signaling only for circuit packs that can receive their signaling packets over
the Packet Bus, e.g., the TN464F UDS1 circuit pack and the TN556B
circuit pack
The TN2402/TN798 Processor circuit pack is not equipped with a direct interface
to the Packet Bus. In order to use the Packet Bus, PKT-INT 2 (1A2) connects via
the Processor circuit pack’s TDM Bus interface to a special Bus Bridge module on
the TN799 C-LAN circuit pack. That module provides a Packet Bus interface on
one side and a TDM Bus interface on the other, and PKT-INT 2 is therefore able to
access the Packet Bus through it.
PKT-INT 2 is enabled only when the following conditions are met:
■
The system contains at least one TN799 C-LAN circuit pack, and
■
The Packet Intf2? field on the Maintenance-Related System Parameters
form is set to “y”.
