H-E1T1-IP E1/T1 over IP TDM Transport System
Our H-E1T1-IP systems offer you a way to extend the range and functionality of your E1 or T1 connections. A TDM over IP bridge is a device that transports the E1/T1 signal over an IP based Ethernet network. This is useful for Telecom providers as a means of providing T1 service over their existing packet switched infrastructure. Another popular application is providing T1 links over low cost wireless LAN bridges, eliminating the need for much more expensive microwave radio links. Wireless links of up to 20 km are possible with this approach. H-E1T1-IP systems operate transparently providing a seamless connection to all equipment with a physical E1/T1 interface such as a PBX, Cellular base station, SS7 signaling equipment, or voice mail system. We provide TDM over IP systems for up to 16 T1 or E1 lines.
Product features
• Up to 16 T1 or E1 links can be multiplexed over IP with a single device
• provides transparent links over packet based IP networks
• Provies support for both point to point and point to multipoint applications
• Supports SNMP for remote network managment and monitoring
• Support for fractional E1/T1 of both framed and unframed interfaces
• Minimal cost for installation and support
