Programming A Digital Trunk; S0 Module; S0 Ports - Siemens HiPath 1100 Programming Manual

Step by Step

Programming a Digital Trunk

HiPath 1100 systems can be equipped with digital lines
by installing a S (ISDN access) and a TME1 (E1 CAS or
0
S2 access) module.
S Module
0
Each ISDN access provides two communications chan-
nels (64 kbps each)as well a capability for sharing appli-
cations such as video conferencing or Internet access.
Depending on your carrier, some facilities may be pro-
vided, including Caller ID, Caller ID Blocking, Direct Dial-
ing to Extensions. 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 digital ISDN lines are available, the settings
for DID Prefix, External Number Phonebook, Country
Code, and Area Code must be configured.
S Ports
0
This setting specifies the operating mode for the S
module maximizing the system's port usage.
This option is best for the HiPath 1190 due to its high
port capacity. The goal is to obtain the greatest possible
number of extensions/external lines allowed according
to the following port detection rules:
• External line and extension (default): Each port will
decrease the number of external line slots by 2 and
extension slots by 1. The connection may be PP ,
PMP or S Bus line (see item "S0 Line Operation
0
Mode").
• External line only: Each port will decrease the num-
ber of external line slots by 2. The connection must
be PP or PMP . If it has been previously configured as
S Bus line, the connection will be automatically re-
0
versed to PP (which is the default).
• Extension only: Each port will decrease the number
of extension slots by 1. The connection must be a S
Bus line. If it has been previously configured as PP
or PMP , the connection will be automatically re-
versed to S Bus line.
