What I understood about SS7
Wednesday, February 17th, 2010SS7 is an example of CCS (Common Channel Signalling ) Protocol
- It is not a single protocol
- It is a suite of Protocol
- It is not an access protocol
- It is a net work protocol
- It is point to multipoint
ISUP(ISDN user part) and TUP (Telephone User Part) are in the call control layer
There is MTP (Message transyer layer ) which has three layers:-MTP1 , MTP2 , MTP3
Here in MTP1 (OSI -Physical layer ) has E1,T1
My opinion
So we have E1 , T1 links available in MTP1 layer , is this enough for the PBX . ie If we take the E1 link from MTP1 to the foneBRIDGE , it should work.
Etisalat :- ISDN Basic Rate Interface (BRI)
Wednesday, February 17th, 2010ISDN Basic Rate Interface (BRI)
ISDN BRI offers either 64Kbps or 128Kbps data transfer rates. Calling Line Identification Presentation (CLIP) is offered as standard.
Basic Rate Interface (BRI) can support two dial-up services at the same time. One line could be used for data access and the other for voice calls, for example. A maximum of 8 multi-subscriber numbers can be associated with a Basic Rate ISDN line.
Etisalat :- Primary Rate Access (PRI)
Wednesday, February 17th, 2010A 2Mbps pipe from the exchange to your business provides thirty channels, each at speeds of 64Kbps. They can be used for voice and data dial-up services.
With ISDN PRI, almost all modern voice and data communication systems from PBXs, mainframe and distributed systems through to your company LAN/WAN can be connected to your ISDN service.
The use of routers, multiplexers, ISDN controllers and video/audio conferencing units is also supported.
Additionally, Digital Telephone Switches can use our Direct Inward Dialling (DID) facility over PRI. DID offers a single interface for up to 30 concurrent calls, as well as for up to two hundred free DID extensions.
