Planning for installation
Trunk configuration information
Trunk configuration on the Remote Office 9150 unit consists of defining the
ISDN BRI lines from the central office and assigning one or more B-channels, if
desired, to trunk groups.
Numbering plan
You must assign a trunk access code to each trunk group at the Remote Office
9150 unit site. A trunk access code is the number that must be dialed to obtain an
outgoing trunk. In addition, you must define special prefix (SPRE) codes for the
following features if you want to use them:
n
paging
n
to go online or offline (for more details, see "Online/offline table" on page
46)
n
local calling
This allows analog or ATA-equipped station users to change the outgoing
call mode to locally controlled mode. (Host-controlled mode is the default
mode when users go offhook on analog or ATA-equipped stations.)
n
registration and deregistration
The registration SPRE code is used to register the station user with a multi-
user or dynamic port.
The deregistration SPRE code disengages the user from the port so that
another user can use it. The user is put into not logged in mode.
All trunk access and SPRE codes are automatically defined in Configuration
Manager with a pound sign (# in North America) so that there are no conflicts
with host PBX dialing plans. The maximum length of each code is three digits in
addition to the pound sign. For a list of the default SPRE and trunk access codes,
refer to the "Remote Office 9150 Configuration Information—Dialing Plans"
form on page 354.
Note: You can change the defaults if you wish.
