One Stop Systems / SBE PTMC-C4 Series

  • HDLC/SS7 Communications Module
  • Up to 128 DSO Channels
  • (4) RJ48c Connectors


The One Stop Systems / SBE PTMC-C4 series is an HDLC/SS7 communications module. The board is in the form of a standard PTMC module and has four shielded RJ48c connectors at the front bezel. It uses the Conexant CN8474A Multichannel Synchronous Communications Controller (MUSYCC) as the protocol-processing engine. This component supports up to 128 DS0 channels. Its primary function is to translate data between the PTMC CT-Bus, the host PCI bus, and its own T1/E1/J1 ports.

Data can be processed for up to 128 full duplex standard DS0s, hyper channels, and sub channels in HDLC, SS7, or transparent modes. The PCI interface conforms to the PCI 2.1 specification. It transfers 32 bits of data at up to 33MHz. The board is capable of 3.3V signalling and is 5.0V tolerant.

The Lucent T8105 H.110 Interface and Time Slot Interchanger are used to interface to the PTMC CT-Bus connections. The MUSYCC and COMET TDM busses are connected to the T8105, whose H.110 bus is connected to Pn3 of the wanPTMC-C4T1E1. The T8105 also provides time slot interchange and time slot assignment functions.

The T1/E1/J1 interface is presented with shielded RJ48C connectors located on the front panel of the wanPTMC-C4T1E1 module. A software selectable option allows the T1/E1/J1 interfaces to be routed to connector Pn4 for rear I/O support. The board uses the PMC-Sierra Quad COMET T1/E1 framer, which allows software to select between T1, E1, and some J1 modes of operation, with programmable line build out.
