TDM pseudowire access gateway


RAD’s IPmux-1E TDM pseudowire gateway is customer located equipment (CLE)
RAD’s IPmux-1E gateway is designed to meet the requirements of small customer sites. It reduces operating expenses by delivering virtually all TDM, legacy data and LAN services over IP/Ethernet/MPLS networks, while ensuring strict priority to the TDMoIP traffic over the network link. End users continue to receive all familiar services, while carriers and service providers maintain revenues from legacy services. The compact size, ease of installation and support for multiple legacy and next generation Ethernet and IP-based services, make it ideal for small and medium-sized enterprises (SMEs).

Features and Benefits

  • Transmits TDM-based services over packet switched networks (Ethernet, IP or MPLS)
  • Provides analog, ISDN BRI and E1/T1 user ports with echo cancellation
  • Transparent LAN bridging over packet-switched network
  • Fiber and copper Fast Ethernet uplink interfaces
  • QoS support

Further Information

Ethernet access
IPmux-1E answers the growing need of business customers for transparent LAN services (TLS) such as LAN-to-LAN interconnection and Ethernet connectivity to service providers. Enhanced features, such as user LAN port rate limitation enable the adaptation of bandwidth to the transport media. Users can configure the ToS or DiffServ values of outgoing TDMoIP packets, to ensure they receive the required priority by network switches and routers. In addition, TDMoIP frames are assigned dedicated VLAN ID tags to separate user and management traffic and to filter user traffic.

TDM circuit extension
The TDMoIP gateway can provide circuit extension over PSN to any user device with a standard E1/T1 interface. It also offers connectivity to four ISDN BRI S0 channels or four analog voice channels, with optional near-end echo cancellation (up to a full E1/T1), for cases where a large end-to-end delay causes echo, such as in satellite applications. The device supports alarm detection with error statistics, SES/UAS statistics, LOS/AIS physical layer alarms and remote/Local Loop tests. In addition, it supports standard E1/T1 alarms from end to end.

IPmux-1E is equipped with the following interfaces:
  • TDM user port options:
    - Single standard E1/T1 port with echo canceller
    - Four analog (FXS/FXO/E&M) ports with optional echo canceller
    - Four ISDN BRI S0 ports
  • One Ethernet uplink with 10/100BaseT or 100BaseFX interface
  • Optional Ethernet user port with 10/100BaseT interface for LAN connectivity

Service center management
The IPmux-1E features flexible management capabilities, including local management via an ASCII terminal (RS-232). In addition, remote management can be performed either inband or out-of-band, using the network or user ports, while maintaining separation between management and user traffic via the use of VLANs. Advanced FCAPS (Fault, Configuration, Accounting, Performance, Security), service provisioning and diagnostic tools are provided by RADview-SC/TDMoIP, RAD’s network management system, via an SNMP-based GUI. The IPmux-1E also supports a variety of configuration access channels, including Telnet, SNMP, Web server, and TFTP.
