Form Fields
•
equipped
For each RS-232 channel cabled, set equipped to
y
.
•
synch/asynch
This field indicates the operating mode for the channel.
— If channel 5 is cabled through a modem or data set to the switch, enter an
a
. If it accesses a
synchronous modem pool once inside the switch, however, you should enter an s.
— If channel 5 is cabled directly to another system, enter an
s
.
Set the fields appropriately for channel 6. Assignments may be different than channel 5.
•
data rates
Assign data rates for each RS-232 channel. The default value for data rate (1): is 9600. For modems
that AT&T supports, the default value for both data rate (2): and data rate (3): is null (blank).
that AT&T supports, the default value for both data rate (2): and data rate (3): is null (blank).
— If the RS-232 channel is not converted to DCP the data rate administered should match the modem
speed. The following values are typical:
•
If channel 5 is connected through the switch, set data rate 1 to
19200
. Leave data rate 2 and
data rate 3 blank.
•
If channel 5 is connected directly to another system, set data rate 1 to
64000
. Set data rate 2
to
56000
. Set data rate 3 to
19200
.
— If the RS-232 channel is converted to DCP, do one of the following:
•
Set data rate 1 to
56000
(synchronous) if a Modular Processor Data Module (MPDM), Model
M1*, is used on channel 5 for switched RS-232 converted to DCP mode 1. Leave data rate 2
and data rate 3 blank.
and data rate 3 blank.
•
Set data rate 1 to
64000
(synchronous) if a Modular Processor Data Module (MPDM), Model
M1*, is used on channel 5 for switched RS-232 converted to DCP mode 3. Leave data rate 2
and data rate 3 blank.
and data rate 3 blank.
•
Set data rate 1 to any value between
1200
and
19200
(asynchronous) if a 7400A or 7400B
data module is used on channel 5 for switched RS-232 converted to DCP mode 2. Leave data
rate 2 and data rate 3 blank.
rate 2 and data rate 3 blank.
Set the fields appropriately for channel 6.
•
switched/dedicated
RS-232 channels converted to DCP mode 1 or DCP mode 3 via an MPDM/M1* must be administered
as dedicated since these channels can only be used for incoming calls; they cannot be used for outgoing
calls.
as dedicated since these channels can only be used for incoming calls; they cannot be used for outgoing
calls.
— Enter
s
when the channel is connected to the switch through a modem or a 7400A or 7400B data
module.
— Enter
d
when the channel is connected directly to another system or if the channel is converted to
DCP mode 1 or DCP mode 3 via a MPDM/M1*, data module.
