otherwise a normal extension and can receive calls directed to it as for
other extensions.
Trunks
7.12 Trunk lines are programmed in a similar manner (for similar
reasons) to extension lines (see paragraph 7.09). They are allot-
ted an equipment (port) number, a trunk code (which defines the type
of trunk - CO, DISA, etc.), a Busy Lamp, and an LDN (listed directory
number position on the console). In addition, they may be assigned a
"Day" and "Night" option which enables the trunk to ring a particular
night bell and/or directly access a particular extension or Hunt Group.
A Class-of-Service code can be provided for dial-in trunks to enable
them to have access to features such as paging.
Trunk Groups
7.13
In addition to the individual trunk program (paragraph 7.12) one
or more trunk lines may be programmed into groups having
particular requirements. They must be given an access code and may
be toll-denied. Note that toll denial requires that both the extension
and the trunk group must be programmed with toll denial to prevent
toll calls. This allows a given extension to be denied toll access on one
group of trunks but not on another. Finally, the trunk groups must each
. . be given a 4-digit type code, which defines such things as answer
supervision, toll reversal, message registration and DTMF or DP signal-
ing. One group can also be programmed to overflow into another
similar group when the former group is busy.
Toll Control
7.14 The Multi-Digit Toll Control program allows a customer to
specify the toll calls which may be made from any extension
within the PBX. The level of toll control for any extension can range
from full capability (Le., ability to dial any toll call) to being restricted
to calling a single directory number. An extension can also be inhibited
from making any toll call. A full description of this program is given in
Section MITL9105/91 lo-096-212-NA,
Traffic Measurement
7.15 The Traffic Measurement program allows a user to output traf-
fic data to a customer-provided terminal (printer or magnetic
tape recorder), which is connected to the RS-232 data port of the PBX.
Alternately, the data may be transmitted to a remotely located terminal
(using a modem) over the public telephone network Full details are
contained in Section MITL9105/911

Station Message
7.16 The Station Message Detail Recording program allows a busi-
ness to analyze its telephone costs by collecting data for each
outgoing and/or incoming trunk call. The data contain details such as:
