TMST1 (for U.S. only)
Introduction
The TMST1 trunk board connects a digital trunk with HiPath 3750 and HiPath 3700. This is how
an ISDN primary multiplex connection is implemented (PRI, Primary Rate Interface) by means
of a T1 interface.
It can also be used for the following layer-1 operating modes:
●
Super Frame SF
●
Extended Super Frame ESF
A maximum of eight TMST1 modules can be used in a HiPath 3750 or HiPath 3700.
Rather than connecting to a main distribution frame (MDF), the TMST1 board connects to a
channel service unit (CSU). The CSU supplies the required secondary protection.
Switches and LEDs
The lockout switch alerts the system software that the module will be removed so that no new
calls are routed to the board.
