PKT-INT (Packet Interface Circuit
Pack)
The Packet Interface (PKT-INT) circuit pack (TN1655) serves as an interface
between the Switch Processing Element (SPE) and the Packet bus in the
Processor Port Network (see the figure in the following pages).
The PKT-INT supports links used for call setup of all ports located in Expansion
Port Networks (EPNs). Therefore, if the PBX system is equipped with the
Standard Reliability configuration (without duplicated SPEs), a failure of the
Packet Interface circuit pack will prevent call origination and tear-down from
telephones and trunks connected to EPNs. In addition to affecting telephone
service, a failure of the Packet Interface circuit pack will affect service provided
by the following circuit packs that connect to the Packet bus:
■ TN464C Universal DS1 circuit pack — ISDN PRI service
■ TN553 Packet Data Line circuit pack — System Port feature used for
connectivity to features such as Call Detail Recording and dial-up
administration.
■ TN556 ISDN-BRI Line circuit pack — ISDN BRI service
■ TN577 Packet Gateway circuit pack — BX.25 links used for services
requiring BX.25 links such as AUDIX and Distributed Communications
Systems
If the PBX system is equipped with the High Reliability or Critical Reliability option
(i.e. with duplicated SPEs), and if a failure of the Packet Interface circuit pack on
the active SPE causes a MAJOR alarm, a SPE interchange will occur if the state
of health of the standby SPE is high enough to permit an interchange. A MAJOR
alarm caused by a failure of a Packet Interface circuit pack on the standby SPE
will drop the state of health of the standby SPE which prevents any attempt to
interchange SPEs.

2. If a spontaneous interchange has occurred (as indicated by STBY-SPE error type 103 or the
display initcauses screen), and handshake is down, (check with status spe), replace the alarmed
circuit pack on the standby SPE. If handshake is up, execute a test long clear of the alarmed circuit
pack and follow recommended procedures.
