Digital trunk settings
HiPath 1100 systems can be equipped with digital
trunks by installing an S
0
(ISDN access) and a TME1 (E1
CAS or S2 access) module).
S
0
module
Each ISDN access provides two communications chan-
nels (64 kbps each) as well as a capability for sharing ap-
plications such as video conferencing or Internet ac-
cess. Depending on your carrier, some facilities may be
provided, including Caller ID, Caller ID Blocking, Direct
Dialing to Extensions, and so on if activated by the car-
rier. The HiPath 1120 can be equipped with a 2-port
module; the HiPath 1150 with a 2-port module or one 5-
port module; and the HiPath 1190 with two 2- or 5-port
modules.
When only ISDN digital lines are being used, the follow-
ing functions must be configured: DID, external number
registration, area code, country code.
When the Fax/DID module answers calls, it plays
one of the twelve greeting messages recorded,
unless it is waiting for user input (in the case of
a DID). When the Fax/DID module answers a call
and forwards it to an extension (the call is ringing
somewhere), that call is no longer considered
one of the eight calls that is keeping the Fax/DID
module busy. In sum, once the Fax/DID module
forwards a call to an extension, the channel is
available for another call.
