Assigning Pools And Lines/Trunks (Hybrid/Pbx Mode) - AT&T MERLIN LEGEND Release 3.1 System Planning Manual

Assigning Lines/Trunks to Data and Video Stations
Assigning Pools and Lines/Trunks
(Hybrid/PBX Mode)
If you want the voice and data station to make and receive outside calls on a
specific trunk pool, assign a Pool button.
To dedicate a specific line/trunk or pool to receive outside data calls, assign a
personal line or pool to a data station or DHG.
To dedicate specific lines/trunks for use in data communications only (such as
PRI channels or other special data lines), consider grouping those lines/trunks
in a pool.
If the system uses ARS, follow the instructions on ARS earlier in this book to
specify routes for outgoing data calls.
To restrict non-data users from dial access to data trunk pools, use the "Pool
Dial-Out Code (Hybrid/PBX Only)" instructions later in this chapter.

appropriate button. For ISDN terminal adapter data stations, include the
line/trunk number.
