DCP Operation

Remote DCP access is accomplished using either the primary or secondary channel (if available)
of the VF line. Using the primary channel gives a much faster response time due to the higher data
rate, but it also interrupts data flow because primary data is stopped when Remote mode is active.
Once Remote mode is terminated, the primary channel is automatically made available for data
transmission.
Unlike primary channel communications, the secondary channel operates at a slower data rate and
does not interrupt data flow. (V.34, V.32 terbo, V.32bis, V.32, and TMp are the only modulations
available for the secondary channel.)
NOTE
When initiating a Remote function from a TMp tributary modem,
primary channel operation is not available. Also, if the tributary
modem is not on the control modem’s poll list, the error message
No Trib Session appears when the function is executed.
To access the Remote branch, make the following selections:

NOTE
If a connection is not established between a local 3900 Series
modem and a remote 3900 Series modem, the LCD displays
Remote Mode Fail–No Circuit. Return to the Top-Level menu.
For Trellis Multipoint (TMp) control modems, you must specify the network management address
of a tributary modem. The following display does not appear in point-to-point or Trellis
Multipoint tributary modems.

The address field (xxx) displays the network management address of the modem to be accessed by
the Remote function. The valid address field range is from 001 to 256.
To increment digits within the address field (xxx), use the

keys to position the cursor
( _ ) under the digit to be incremented. Press the F2 (

Press Enter (Ent) to select the modem that will be accessed by the Remote function.
