Pseudowire TDM over IP Products

Close

Coming Soon

The PacketLINK family will provide single and multi-port connectivity solutions for Nx64kbps E1/T1 and E3/DS3/T3 services across IP networks, including either simple point-to-point links or more complex WAN infrastructures.

The PacketLINK family will provide a range of solutions for the delivery or extension of legacy services across IP backbone networks using TDM over IP / TDM over Packet / TDM over Ethernet / TDM over Pseudo-wire technologies.

The PacketLINK key features will include (model version dependent) *:

  • Support for IETF-PWE3 (pseudo-wire), SAToP and CESoPSN transport mechanisms.
  • Support for IP, MPLS and MEF8 (Metro Ethernet) tagging.
  • Support for three E1 framing modes - Framed, Unframed and Multi-Framed with CAS signaling.
  • Support for three T1 framing modes - Unframed, ESF and SF.
  • Support for two E3/DS3 framing modes - Unframed and Framed
  • Support for point-to-point, point-to-multipoint and drop and insert applications.
  • Support for Internal, External, Adaptive, Recovered clock and Asymmetrical (One-Clock and Two-Clock) options for the E1/T1 TDM port synchronization. Automatic clock priority selection with fall back.
  • Support for Internal, External, Adaptive and Recovered clock options for E3/DS3 synchronization. Automatic clock priority selection with fall back.
  • Support for CESoPSN payload mechanism to support the fractional E1 with data rate of 64Kbps to 2.048Mbps (DS0 timeslot level). User configurable data rate from 64kbps to 2048kbps, in steps of 64kbps.
  • Support for CESoPSN payload mechanism to support the fractional T1 with data rate of 64Kbps to 1.544Mbps (DS0 timeslot level). User configurable data rate in steps of 64kbps.
  • 1+1 Ethernet link redundancy
    • Rapid Spanning Tree Protocol.
    • Ethernet Port Trunking
  • Configurable payload size for each bundle
  • Support for 802.1Q based QoS, 802.1p based packet priority.
  • Port Based Priority (Classifying Services)
  • DSCP (Differentiated Services / Diffserv), and 802.1Q / 802.1p based packet tagging and prioritization
  • Flow Control in an Ethernet Packet Networks: (Regulating Traffic)
  • Port / Customer based bandwidth allocation (Port Rate Limiting)
  • Separate IP Address for TDM traffic and equipment management

PacketLINK: TDM over IP - Fractional E1 links

PacketLINK products may be used to provision Telco services over an IP network, or to extend TDM connections between devices across an IP backbone. Telecom and enterprise users can save network and equipment cost and genereate additional revenue by offering different types of service over a single packet switched infrastructure.

Telecoms Service Providers might, for example, use this to provision connection for both Data services (via Ethernet) and ISDN-30 services for non-SIP PBX Voice Trunks (via E1), both over a single IP service connection
