E1 CAS protocols
The Dialogic GlobalCall 4.0 Protocols for E1/CAS are installed with Dialogic SR 6.0. You
specify the protocol to use when you add the E1 CAS span in the TeleVantage Administrator,
as described in Chapter 5 of Administering TeleVantage.
Additional required hardware for E1 service
No additional hardware is required to support E1 CAS service.
To support E1 ISDN service, you need the following:
Q Network Termination Unit (NTU). Most ISDN installations include an NTU from the
phone company, so you should ask your phone company for details. Connect the NTU
between TeleVantage and the digital line coming in from the phone company.
If you do not have an NTU available, you can use a standard Channel Service Unit
(CSU) that handles Extended Superframe Format (ESF) instead.
Q Network Termination type 1 adapter (NT1). Typically supplied by the phone
company.
Q Cable. Connects an NTU to the Dialogic board. When ordering one from your supplier,
specify the following:
Q Recommended cable type. Twisted-pair, in which each of the two pairs is
shielded and the two pairs also have a common shield.
Q Connectors. The cable connects to the board via a RJ-45 Modular connector on the
front or rear bracket of the board.
Note:
A Digital Service Unit (DSU) is not required because the Dialogic boards supply DSU
functionality.
