and is optionally delivered to the outgoing PRI, depending on the
CPIALLOW field in table CALLATTR. However, no check occurs to ensure
the number is valid in format or in content.
Supplementary/account codes
The suppcode/account code is a multidigit DTMF code used to allow
chargeback of calls to projects, departments, or accounts. Calls that involve
NCS/DAP initiation of collection of these codes use suppcodes. When codes
are invoked in-switch, these are called account codes. Throughout this
chapter, supplementary code collection means retrieval of digits based on a
request from the NCS/DAP. Account-code collection refers to the in-switch
retrieval of digits based on table AUTHCODM datafill.
Suppcode or account code collection is determined by the account code
length (ACCTLEN) parameter in table AUTHCODM. This parameter
specifies the number of account code digits to dial. If ACCTLEN > 0, the
call is processed as in-switch. If ACCTLEN = 0, suppcodes are collected
through NCS/DAP-based methods. With VNET calls, the account code
length (ACCTLEN) can be 0 to 11 digits.
Supplementary code redial
This feature allows the user, after reorigination, to automatically redial the
supplementary codes that were entered on the previous call by pressing the
star (*) key. After the user presses the star key, the previous supplementary
codes are used exactly as if the user manually re-entered them. This redial
feature is available on all calls that support supplementary code collection
and allow reorigination.
Voice call suppcode/account code collection
If the DMS-250 switch receives a voice call requiring a suppcode, it sends a
400-Hz prompt tone, then collects and processes the number.
Data call suppcode/account code collection
If the DMS-250 switch receives a data call requiring supplementary or
account code collection, it does not send a prompt tone; it collects the
number from table MLTATTR.
Datafill
To use the suppcode collection feature, enter a MLTIDX value in the
LTCOPT field of table LTCALLS. Enter a corresponding index value and a
default number (up to 11 digits) in the appropriate fields of table MLTATTR.
Table 7-12 shows example entries for table MLTATTR.
