ESI-50L Programming Manual Function 2: CO lines
E.4
Function 22: Translation table programming
Function 221: Centrex/PBX access code
If the system is to be used behind Centrex or another PBX, you must list the dial access code used to gain
access to a CO line from Centrex or the PBX, so that toll restriction can ignore the access code digit(s). Users
must dial the access code after accessing a line by either:
(a.) Dialing 9, 8, or 71–76
or
(b.) Pressing a line key (if programmed)
The access code can be one or two digits — e. g., 9, 81, etc. — and must be programmed for each line group.
Default: 0.
Note: You must set the flash duration in Function 151 (page D.3) for the requirements of the host switch.
Function 222: Toll restriction exception tables
The system’s toll restriction is based on outbound calls being defined as either toll calls (i.e., calls in the deny
table) or non-toll calls (calls in the allow table). Four tables exist for this purpose:
1. Allow exception table (programmable). Up to 100 entries; no entry can exceed 26 digits.
Default: No entries.
2. Deny exception table (programmable). Up to 100 entries; no entry can exceed 26 digits.
Default: No entries.
A number listed in the allow exception table — e.g., a branch office or vendor’s location — will be allowed to
all stations, regardless of how they’re set in Function 32 (see page F.6). Conversely, a number listed in the
deny exception table (e.g., a “1-900” number) will be denied to all stations.
3. Fixed allow table (not programmable).
Default: 1800, 1888, 1877, 1866, 1855, 1844, 1833 and 1822.
4. Fixed deny table (not programmable).
Default: 976, 1976, 1xxx976, 900, 1900, 1xxx900, 555, 1555, 1xxx555, 0, 10, 411, 1411 and
11+-digit restriction.
In extension feature authorization (Function 321; see page F.6), each extension is set to be toll-restricted one
of two ways: TOLL CALLS = Y (yes) or TOLL CALLS = N (no).
Note: System speed-dial numbers (Function 17; see page D.10) are not affected by toll restriction.
If TOLL CALLS = Y (yes) in Function 321 (page F.6), the system checks the number dialed against the Deny
Exception table. If the number matches an entry in this table, the call is restricted. Otherwise, it’s allowed.
If TOLL CALLS = N (no) in Function 321 (page F.6):
1. First, the system checks the number dialed against the Allow Exception table.
If the number matches an entry in this table, the call is allowed.
Otherwise . . .
2. The number is checked against the Deny Exception table.
If the number matches an entry in this table, the call is restricted.
Otherwise . . .
3. The number is checked against the Fixed Allow table.
If the number matches an entry in this table, the call is allowed.
Otherwise . . .
4. The number is checked against the Fixed Deny table.
If the number matches an entry in this table, the call is denied.
Otherwise . . .
5. The call is allowed.
