TST1 (for U.S. only)

Introduction
The digital T1/PRI trunk module (TST1) connects the communications server to primary rate
interface (PRI) ISDN via a T1 interface.
There are two versions of this board:
S30810-Q2919-X - for use in the HiPath 3550 (wall housing)
●
S30810-K2919-Z - for use in the HiPath 3500 (19-inch housing)
●
The board can also be used for the following layer-1 operating modes:
Super Frame SF
●
Extended Super Frame ESF
●
Board usage is subject to the following restrictions:
Only one TST1 board allowed (primary multiplex access)
●
For slot 7 or 9 only
●
Rather than connecting to a main distribution frame (MDF), the TST1 connects to a channel
service unit (CSU). The CSU supplies the required secondary protection.
