PKT-INT (Packet Interface)
The Packet Interface (PKT-INT) interfaces between the Switch Processing
Element (SPE) and packet endpoints (such as ISDN-BRI stations or ISDN-PRI
trunks). Two instances of PKT-INT are provided on the TN2401/TN794 NetPkt
circuit pack:
■ PKT-INT 1 communicates through the TDM bus only
■ PKT-INT 2 communicates through the Packet bus only
The Packet Interface (PKT-INT) appears only in R7si and later systems. Pre-R7si
systems use the TN778 Packet Control (PKT-CTRL) to provide the Packet Bus
interface for the SPE.
If the system is equipped with the Standard Reliability configuration (without
duplicated SPEs), a failure of both Packet Interface instances prevents call
origination and tear-down for telephones and trunks provided by the following
circuit packs:
■ TN464C, TN2464 Universal DS1 circuit packs - ISDN PRI service
■ TN767E DS1 Interface circuit pack - ISDN PRI service w/o Packet Bus
■ TN556B/C, TN2198 ISDN-BRI Line circuit packs — ISDN BRI service
■ TN2185 ISDN Trunk-Side BRI - ISDN-BRI Trunk service
■ TN566, TN2208 Multi-Function circuit packs- ASAI-over-Ethernet service
■ TN800, TN801, TN803 MAPD circuit packs - LAN Gateway Emulation
■ TN802 MAPD circuit packs - IP Trunk Emulation, Media Processor
applications
■ TN799 CLAN - Ethernet and Asynchronous PPP service
A failure of only one PKT-INT instance may allow some links to transfer to the
other PKT-INT instance.
