Appendix D: Applications and Switch Administration
Note: This section should not be used as a step-by-step
administration guide nor is it intended to replace the
information provided in the switch administration
manuals. Only those procedures and entries that are
essential to this application will be covered. It is therefore
recommended that the proper administration manuals be
consulted before any steps are taken. Furthermore,
certain fields in various administration screens and
procedures have been left blank or their default values
have been used because the proper entry for those fields
will vary from switch to switch. It is left to the discretion
of the network administrator to properly populate those
fields.
HSL Options
Since the AC will establish all connections, the HSL will not be
used for dialing and the Dialing Method can be set to MANUAL.
In addition, the FEP and CC do not support a DTR lead on their
V.35 interface and require DSR On from the HSL. As a result, the
following options are set for this permanent application.
DIAL = MANUAL
SPEED = 56KBPS
DUPLEX = FULL
ANSWER = AUTO
The HSL Loopback option should be set to V.54 if the data module
(for example, a DSU) at the other end supports V.54 loopback.
Data Invert should be set to ON if a 64 Kbps call is established
with a data module that performs bit inversion at 64 Kbps, such as
the MPDM.
These settings are described in Chapter 4, ''Options.''
Generic 3 Administration
Station Administration
The administration of the HSL extensions in this application is
similar to that for the Generic 1 as described in the switched video
application. In this case, the Data Module form is used to create
extensions 5000 and 5001.
Trunk Group Administration
To support a PBX to PBX AC, a static trunk group consisting of a
single DS0 is established. This allows signaling (on/off-hook) to
be passed between the Generic 3 and Generic 2. To administer
PERM CONN = YES
LOOPBACK = AT&T
DSR = ON
DTR = IGNORE
