D/I Mux III - SO/S Card

Smart Omni OrderWire/Station Coastcom's Smart Omni Orderwire/Station (SO/S) Channel Card and the D/I Mux III make network maintenance easy.

Typical Applications

• SO/S permits voice communication in both directions on a "party line" basis
  with all other units on a single DS0 in point-to-point and drop/insert networks.
  It works directly with a 2-Wire DTMF telephone.
   
• OrderWire channels allow the network manager to call several locations at once. Directions can be given to one location and results observed at another to facilitate servicing.
   

Feature Advantages

• Traditional orderwire circuits require that you call every station in a network.
  Coastcom's smart Omni Orderwire units provide the flexibility to contact just one
  station using a customer's assigned address, or all stations that share the same address.
   
• Communicating with a station is as simple as dialing the customer assigned address number followed by a '#'. Addresses are assigned by software and can range from 1 to 999 to handle large networks. Any and all addresses may be active at the same time in the same conversation.
   
• Coastcom's built-in quiet circuit helps eliminate accumulated noise.
   
• A 2-Wire RJ-11 jack interface eliminates the need for special 4-Wire telephones. Off hook, ringing, and DTMF (touch tone) dialing are supported.
   
• The system offers the flexibility to wire a telephone with the standard T/R connector or a standard "modular phone jack" (RJ11) on the front panel.
   
• A station can signal calls with an on-board "Sonalert" or 20 Hz ringer.
   
• All options on the card can be remotely provisioned from a system control terminal
