CAUTION:
A detailed flowchart for isolating and resolving Packet Bus faults is included
in
Chapter 9, ‘‘Packet Bus Fault Isolation and Correction’’
. This flowchart,
along with the other information presented in the chapter, can help in
resolving problems that are not isolated to the Packet Control. Whenever the
repair procedures for this Maintenance Object refer to Packet Bus and/or
Packet Control maintenance, be sure to reference Chapter 9 in addition to
the MO documentation for Packet Bus.
The TN778 Packet Control circuit pack is the hardware component that serves as
the interface between the SPE and the Packet Bus. It terminates the Link Access
Procedure D (LAPD) protocol and provides support for thousands of signaling
links. As shown in
, a Packet Control link generally
terminates on the Packet Control circuit pack and a packet endpoint which is
connected to a Packet circuit pack. An ASAI adjunct is an example of a packet
endpoint, and a TN556 is an example of a Packet circuit pack. In G3iV1.1-286 or
G3iV2-386, the following Packet circuit packs (packs that can connect to the
Packet Bus) are available:
■
TN556 ISDN-BRI Line Circuit Pack
■
TN570 Expansion Interface Circuit Pack
■
TN771 Maintenance/Test Circuit Pack

If the specified Packet Control circuit pack is in the active SPE, it must first be busied-out
via the busyout packet-control C command. After testing has completed, the Packet
Control circuit pack should be released from the busyout state via the release
