T-1 Trunking

The T-1 trunk card provides the
circuits. The T-1 trunk card supports the standard D4 framing format with Alternate Mark
Inversion (AMI) coding. The system can support TIE, loop start, ground start, and DID
signaling per channel.
The T-1 trunk card can be used to connect 24 lines (24 channels per T-1 circuit) from a CO to
the system. These lines can be any mix of inbound WATS, outbound WATS, standard DDD
lines, DID lines, or TIE lines. The system also supports Fractional T-1 Service. The
Digital Systems use the TIE signaling simulation from the CO to add the additional protocol of
DID.
T-1 trunking provides services called Automatic Number Identification (ANI) and Dialed
Number Identification Service (DNIS). The T-1 feature supports both of these services. The

Text Messaging (Silent Response)

The Text Messaging feature allows a station user to use text messages to respond to a caller
that has either Camped-On or has used the Off-Hook Voice Over (OHVO) feature to alert a
busy station of a waiting call or message. The camped-on station may respond to the caller
via the personalized, custom, and response text (LCD) messages. The text messages appear
on the calling party LCD display. The calling (originating) station and receiving station MUST
be a digital telephone. The receiving station MUST also be programmed to allow OHVO calls.

Toll Restriction (Table Driven)

The system provides a flexible means of providing toll restriction to internal stations of the
Triad 1/2/3
for night mode operation these station COS' work in conjunction with a CO line Class of
Service to allow for customized toll restriction. Two Allow and Deny tables along with four
special tables afford the system administrator to devise a variety of complex toll restriction or
dialing privilege schemes.

Canned Toll Restriction

The system provides an easy means of applying the most common form of toll restriction
where 1+ and 0+ along with 976, 555, and 411 type of calls are denied and 1-800, 1-888, 911,
1-911, and 1-611 type of calls are allowed. This canned toll restriction is applied through the
use of a single pre-built COS and can be assigned to stations using range programming.
Triad 1/2/3
Digital Systems support ANI, DNIS, or an ANI and DNIS combination on a per
System. Each station is assigned a Class of Service for day mode operation and one
