Features and Services
Feature operation
To access a Data Unit (DU), the user dials the Access Code (ACOD) of the
route data block. If a DU is available, a connection is made. If a DU is
unavailable, the user receives this message on the terminal screen: “ALL
PORTS ARE BUSY. ACTIVATE RING AGAIN?” Select Ring Again and
wait until a DU port becomes available.
When a user dials a data port, the request is placed in the Ring Again queue
until a port becomes idle. When an idle port is located, the calling party is
notified and the port is reserved for eight seconds.
Data Port Verification (DVS)
Any applicable telephone with Data Port Verification Allowed (ADV) Class
of Service can place a call to a specific Add-on Data Module (ADM) in a
route by going off-hook, receiving dial tone, and dialing:
SPRE + 70 + ACOD + mmm
where:
The selected ADM trunk is seized if it is in not busy, maintenance busy, or
disabled state. Once the call is established, it is treated as a normal ADM
trunk call. If the selected trunk is in busy, maintenance busy, or disabled state,
the call originator receives an overflow tone. No tone is returned when
keyboard dialing is used.

Trunk Hunting provides either Linear Hunting or Round Robin Trunk
Hunting for outgoing trunks in a route.
SPRE = special prefix
70 = special access code for the Data Port Verification (DVS)
