Short description:

Single channel HD-Voice, digital EQ, USB control

01-INT-GSM-003

This is a telephone hybrid for the mobile telephone network. It provides 100% separation of the caller send and return audio signals using balanced 3-pin XLR connections. Narrowband 3.4kHz calls are possible using the 2G GSM and 3G UMTS networks; 7kHz HD Voice calls are possible using compatible 3G UMTS and 4G LTE networks with a HD compatible device at each end of the call. The GSM hybrid acts as a normal telephone hybrid when calling land-lines. There is digital processing control of the phone signal with echo cancelling, digital EQ control, and configurable automatic gain control.

The GSM hybrid is a half-width 1U high unit that has an optional rack mounting kit for two units. The front panel has a full size SIM card slot for the network SIM card. There are two SMA aerial connections for mounting the included aerials on the front panel. It also has a large push button for call connection and disconnection.

The rear panel has a 3-pin balanced male XLR for the output connection and a 3-pin balanced XLR female for the input connection. There are two separate 6.35mm jack sockets: one for GPO ring signaling control and one for GPI control of the connect switch. A type-B USB socket connects to a PC for all dialling and remote control functions. There is a 5 pin connector for 12V DC power connection using the included power supply.

A comprehensive software application is included for remote control and configuration. This includes input and output metering, level control, dialling, number recognition, and signal strength indication.
