Comtrend’s FM-60 is a flexible transmission system, which provides voice and data applications by time division multiplexing and demultiplexing on 2.048 Mbps E1 signals. Timeslot interchange technique is applied to provide timeslot assignment and timeslot interchange capability, so that any 64 Kbps or Nx64 Kbps user-signal can be assigned and cross-connected to any E1 timeslot.

The FM-60 has a compact design. It has nineteen slots. Four slots are for common units; and fifteen slots are for channel units, which provide versatile user services. All the channel units are hot-swappable, and can be placed in the FM-60 simultaneously, in any combination.

The FM-60 features powerful diagnostic capabilities. Several types of loopbacks can be activated for the units. Utilezing a built-in SNMP agent, the FM-60 supports network management for operation, administration, maintenance, and provision. It can be managed through Comtrend’s user-friendly GUI management software.

The FM-60 is equipped with two RS-232 ports, and one Ethernet port for management. Moreover, the FM-60 has remote management capability, which allows it to be managed over an in-band E1 timeslot. Utilizing the static routing function, management message can be routed from one FM-60 to another, over an E1 line, greatly extending the remote management capability.
