Features and Services
• Data Access Card (DAC), or
• Meridian Communications Adapter (MCA).
The following types of trunk routes are supported for data port hunting:
• ADM Trunk Routes: Add-on Data Module (ADM) data ports that
interface through Data Line Cards
• Modem Trunk Routes: Modem data ports that interface through
500/2500 Line Cards
• RS-232 (R232): RS-232 data ports that interface through Data Access
Cards (DACs)
• RS-422 (R422): RS-422 data ports that interface through Data Access
Cards (DACs), and
• MCA: Meridian Communications Adapter (MCA) data ports that
interface through Integrated Services Data Line Cards (ISDLCs) or Data
Line Cards (DLCs).
Data ports act only as terminating parties. The user dials the access code of
the trunk route to access the data ports.
Operating parameters
All data port trunks within a route must be of a single type. ADM and MDM
data ports cannot be mixed in the same data port trunk route.
Only an attendant can extend incoming calls from stations or trunks (CO, FX,
WATS, TIE, Direct Inward Dialing [DID], Common Controlled Switching
Arrangement [CCSA]) to data port trunk routes. Calls cannot be extended,
transferred, or conferenced from a station to a data port group.
In Night Service mode, any station can transfer incoming calls to data port
routes.
Trunk access restrictions (TARG, TGAR) should be applied to data port trunk
routes to prevent stations with co-located ADMs from directly accessing data
ports with modems, and vice versa.
