Oveview

This 1U 19-inch rack-mounted PCM multiplexer can provide 30 channels of telephone output. The device uses all-digital circuits, ensuring reliable and stable operation, low power consumption, high integration, small size, and easy installation and maintenance.

Features

The device is capable of monitoring the alarm status of the remote end.

E1 interface complies with the G.703 recommendation and uses all-digital clock recovery and smooth phase-locked loop technology.

Voice interface supports FXO and FXS ports, as well as EM2/4 audio interfaces. FXO ports connect to PBX, while FXS ports connect to user telephones.

It supports calling number display and reverse polarity billing function.

It supports mutual dialing function between various sites.

The device is able to detect whether the remote device is powered off or the E1 is not working when the E1 signal is lost.

Multiple power supply options, such as AC220V, DC-48V/DC24V, etc.

The device is a 1U rack-mountable unit with independent SNMP network management.

The telephone interface comes with lightning protection, meeting the GB/T17626.5 (IEC61000-4-5) short-circuit current wave 8/20μs and open-circuit peak output voltage 6KV standards.
