PKT-INT (Packet Interface)
The Packet Interface (PKT-INT) MO resides on the TN2312AP IP Server Interface
(IPSI) circuit pack and serves as an interface between the media server and the
packet bus.
The TN1665 PKT-INT and TN2182 Tone-Clock circuit packs’ functions have been
moved to the TN2312AP IPSI circuit pack. In addition, the IPSI circuit pack
provides the following functions:
■ PKT-INT packet-bus interface
■ Archangel TDM-bus interface
■ Tone-Clock functionality
■ Ethernet interface for connectivity to media servers
■ Ethernet interface for connectivity to services laptop PCs
■ Maintenance board interface for communication with the PN’s Maintenance
board (in Carrier A or B only)
The TN2312AP IPSI circuit pack is inserted into an PN’s Tone-Clock slot and
provides an Ethernet interface back to the media servers. The PKT-INT interface
on the IPSI is like previous DEFINITY TN1655 PKT-INT boards. However, the
IPSI’s PKT-INT does not support DMI Mode-2/-3 data or BX.25 links.
The PKT-INT supports links used for call setup of every port located in an PN. In a
duplex-reliability system (unduplicated IPSIs), a Packet Interface failure:
■ Obstructs the origination of new calls
■ Causes the termination of stable calls
connected to/through an PN’s stations and trunks. (Duplicated IPSIs help prevent
this in a high- or critical-reliability system.)
