Unless otherwise agreed by the Parties, the CCS protocol used by the Parties shall be SS7.Ĭommon Channel Signaling (“CCS”) is a method of digitally transmitting call set-up and network control data over a digital signaling network fully separate from the public switched telephone network that carries the actual call. It is a special network, fully separate from the transmission path of the public switched network. The base rate is 51.84 Mbps (“OC 1/STS 1”) and higher rates are direct multiples of the base rate, up to 13.22 Gbps.Ĭommon Channel Signaling (CCS means an out-of-band, packet-switched, signaling network used to transport supervision signals, control signals, and data messages.

Synchronous Optical Network (SONET means the optical interface standard that allows inter-networking of transmission products from multiple vendors.

The base rate is 51.84 Mbps (“OC-1/STS-1”) and higher rates are direct multiples of the base rate, up to 13.22 Gbps. Synchronous Optical Network (SONET) is an optical interface standard that allows inter-networking of transmission products from multiple vendors. Traffic control signal means a device, whether manually, electrically, or mechanically operated, by which traffic is alternately directed to stop and permitted to proceed. There are twenty-four (24) DS-0 channels in a DS-1. In the time-division multiplexing hierarchy of the telephone network, DS3 is defined as the third level of multiplexing.ĭigital Signal Level 3 (DS-3 means the 44.736 Mbps third level signal in the time division multiplex hierarchy.ĭigital Signal Level 0 (DS-0 means the lowest-level signal in the time division multiplex digital hierarchy, and represents a voice-grade channel operating at either the 56 Kbps or 64 Kbps transmission bit rates. In the time-division multiplexing hierarchy of the telephone network, DS1 is the initial level of multiplexing.ĭigital Signal Level 3 or "DS3" means the 44.736 Mbps third-level signal in the time-division multiplex hierarchy. Digital Signal Level means one of several transmission rates in the time-division multiplex hierarchy.ĭigital Signal Level 1 (DS-1 means the 1.544 Mbps first level signal in the time division multiplex hierarchy.ĭigital Signal Level 0 or "DS0" means the 64 Kbps zero-level signal in the time-division multiplex hierarchy.ĭigital Signal Level 1 or "DS1" means the 1.544 Mbps first-level signal in the time-division multiplex hierarchy.
