MX100-TG T1/E1 Gateway

The MX100-TG T1/E1 Internet telephony trunking gateway gives the large enterprise and the ITSP unprecedented value in a one-, two-, or four-span gateway. The MX100-TG T1/E1 Gateway is designed to provide connectivity between PSTN, ITSP and ISP carrier VoIP networks, or enterprise private VoIP SIP-based networks. The MX100-TG T1/E1 Gateway is interop-proven with commonly deployed central office and SIP-based telephony servers.

High Performance

Media-processing capability is the most important feature for all trunking gateways. The MX100-TG T1/E1 Gateway, configured with one-to-four T1/E1 interfaces, can process 120 simultaneous VoIP and/or FoIP calls. The MX100-TG T1/E1 Gateway embeds powerful DSP technology with 4800 MIPS processing power, to support G.711, G.729A, G.723, G.168 echo cancellation, DTMF relay RFC2833, and T.38 fax relay.

Rich Features

The MX100-TG T1/E1 Gateway offers the features to support many applications, including:

  • Flexible digit translation
  • Up to 500 routing rules
  • Voice announcement and 2nd-stage dialing
  • Auto dialing
  • DTMF detection and call-progress tone detection
  • Early cut through
  • Play ring-back tone
  • T.38 fax relay
  • RTP proxy for NAT traversal


The MX100-TG T1/E1 gateway supports user-side ISDN PRI connections to class 4/5 switches offered by Nortel, Lucent, Alcatcl, Siemens, Huawei, ZTE, and others. It also supports network-side ISDN PRI connections to ISDN PBXs.
The MX100-TG T1/E1 gateway is standards-based and capable of interoperating with SIP-based application servers, media servers and large variety of IADs.


As with other New Rock products, the MX100-TG T1/E1 gateway supports both Web and text-based configuration, along with the TR-069 protocol for centralized remote management for configuration, firmware upgrade, log file download, statistics collection and event alarms.
