Outgoing Outside Data Calls
PLACING A DATA CALL
5-8 Data Calls with Digital Voice and Data Equipment
You use outgoing modem pools to place data calls from digital stations to:
Computers or data terminals outside your MERLIN II system. These calls
go out over standard telephone lines.
• Computers or data terminals connected to analog voice terminals in your
system.
To make these calls, you place an internal data call to an outgoing modem
pool using either the station number for a specific modem pool member or a
3-digit data hunt group number. Then you have the modem dial the number
you want to reach.
If you have more than one outgoing modem pool, consult
NOTE:
your data information sheet or talk with your administrator. He or
she can help you select the modem pool with the appropriate speed
and line assignments for your data call.
The procedure below shows how to p!ace a data call from a 7406 digital voice
terminal or a PT510D using the 2212C modem. If you have a different type of
modem, follow the instructions provided with the modem.
This procedure applies to placing outside data calls manually
NOTE:
using just the keyboard. If you have a PT 510D, you may want to set
up Directory entries for automatic dialing of outside calls through
modem pools. If so, see your User's Guide for that equipment.
