The DS34T104, DS34T102 and DS34T101 have the same functionality as the DS34T108, except they have only 4, 2 or 1 ports and transceivers, respectively. Each E1/T1 transceiver is composed of a line interface unit (LIU), a framer, an elastic store, an HDLC controller and a bit error rate tester (BERT) block. These transceivers connect seamlessly to the TDMoP block to form a complete solution for mapping and demapping E1/T1 to and from IP, MPLS or Ethernet networks. A MAC built into the TDMoP block supports connectivity to a single 10/100 Mbps PHY over an MII, RMII or SSMII interface. The DS34T10x devices are controlled through a 16 or 32-bit parallel bus interface or a high-speed SPI serial interface. TDM-over-Packet Core The TDM-over-Packet (TDMoP) core is the enabling block for circuit emulation and other network applications. It performs transparent transport of legacy TDM traffic over Packet Switched-Networks (PSN). The TDMoP core implements payload mapping methods such as AAL1 for circuit emulation, HDLC method, structure-agnostic SAToP method, and the structure-aware CESoPSN method. The AAL1 payload-type machine maps and demaps E1, T1, E3, T3, STS-1 and other serial data flows into and out of IP, MPLS or Ethernet packets, according to the methods described in ITU-T Y.1413, Y.1453, MEF 8, MFA 4.1 and IETF RFC 5087 (TDMoIP). It supports E1/T1 structured mode with or without CAS, using a timeslot size of 8 bits, or unstructured mode (carrying serial interfaces, unframed E1/T1 or E3/T3/STS-1 traffic). The HDLC payload-type machine maps and demaps HDLC dataflows into and out of IP/MPLS packets according to IETF RFC 4618 (excluding clause 5.3 – PPP) and IETF RFC 5087 (TDMoIP). It supports 2-, 7- and 8-bit timeslot resolution (i.e. 16, 56, and 64 kbps respectively), as well as N × 64 kbps bundles (n=1 to 32). Supported applications of this machine include trunking of HDLC-based traffic (such as Frame Relay) implementing Dynamic Bandwidth Allocation over IP/MPLS networks and HDLC-based signaling interpretation (such as ISDN D-channel signaling termination – BRI or PRI, V5.1/2, or GR-303). The SAToP payload-type machine maps and demaps unframed E1, T1, E3 or T3 data flows into and out of IP, MPLS or Ethernet packets according to ITU-T Y.1413, Y.1453, MEF 8, MFA 8.0.0 and IETF RFC 4553. It supports E1/T1/E3/T3 with no regard for the TDM structure. If TDM structure exists it is ignored, allowing this to be the simplest mapping/demapping method. The size of the payload is programmable for different services. This emulation suits applications where the provider edges have no need to interpret TDM data or to participate in the TDM signaling. The PSN network must have almost no packet loss and very low packet delay variation (PDV) for this method. |
