BT legacy testing
As BT continues to develop its network in accordance with 21CN, several legacy technologies have come back into manufacturers' minds. Due to the extensive knowledge of the engineers at TRaC, we are able to provide BT legacy testing against several technologies, including:
- DPNSS Testing. The Digital Private Network Signalling System (DPNSS) is a network protocol that is used on digital trunk lines to connect two Private Branch eXchanges (PBX) and it supports a defined set of inter-networking facilities. It was originally defined by British Telecom.
- DASS2 Testing. Digital Access Signaling System 2 (DASS2) is a protocol for digital links to the Public Switched Telephone Network (PSTN). It was the first introduction in the UK to an Integrated Services Digital Network (ISDN) and was introduced before the ITU-T Q.921/Q.931 standards. Further information on DASS2 Technology »
- SS7 and C7 Testing. Common Channel Signalling System No. 7 (SS7 or C7) applies to network equipment. The ITU-T standards define the procedures and protocol by which network elements in the PSTN exchange information over a digital signalling network to effect wireless and wired call setup, routing and control, and to provide enhanced call features.
