3.3.20 TMST1 (for U.S. Only)

Introduction

A Digital T1 PRI trunk module (TMST1) connects a digital trunk to the OfficePro to provide primary-rate interface (PRI) ISDN via a T1 interface. It can also be used for the following:

SF
ESF

A maximum of five TMST1 Modules can be used in the OfficePro system.

Rather than connecting to a main distribution frame (MDF), the TMST1 Module connects to a channel service unit (CSU). The CSU supplies the required secondary protection.

Switches and LEDs

The TMST1 includes a service switch. The switch alerts the system software that the Module will be removed so that no new calls are routed to the board.
