Number of IPSI circuit packs per configuration
For configurations where voice bearer is over CSS or ATM, each IPSI usually controls five port
networks. Each IPSI achieves control by tunneling control messages over the bearer network to
PNs that do not have IPSIs. An IPSI cannot be placed in:
● A PN that has a Stratum-3 clock interface
● A remote PN that is using a DS1 converter
● A Survivable Remote Expansion Port Network (SREPN)
A simple formula determines the number of IPSI-connected PNs that should support an S8500
or S8700-series configuration. Divide the total number of PNs in the configuration by five and
add one. The additional IPSI provides fault tolerance. For example, if you have 20 PNs, divide
20 by 5 to get 4, then add 1. You need a minimum of five IPSIs to support the 20 PNs.
For configurations where voice bearer is over IP, there must be one IPSI in each PN.
A direct connect configuration only supports one IPSI-connected PN.
TN2313AP DS1 interface (24 channels)
The TN2313AP DS1 port circuit pack interfaces a DS1 trunk to the switch backplane by port
slots that are standard for DEFINITY products. The TN2313AP is compatible with the following:
● previous 24-channel DS1 circuit packs, including the TN464F, vintage 19 and below
● TN2464,vintage 19 and below
● TN767E DS1.
Except, the TN2313AP does not provide for packet adjunct capabilities. The TN2313AP
supports a variety of applications, including networking of the following:
● DEFINITY switches
● international trunk types
● video teleconferencing
● wideband data transmission
