Table 5-3. Synchronous Data Port Options (1 of 7)

Port Status
Possible Settings: Enable, Disable
Default Setting: Disable
Determines whether the synchronous data port is being used and can be configured.
Synchronous data port options do not appear if Port Status is set to Disable.
Enable – The port is active, and can be used to transmit and receive data.
Disable – The port is not active. When the port is disabled, the following will occur:
No alarms or traps configured for the port will be generated.
LED for the port will be held in an Off state.
Existing cross-connect assignments associated with the port will be cleared. The
message This action will clear any Cross Connections for the Port. Are You
Sure? No appears. If you select:
No – The operation is cancelled. (Pressing either the Esc or Ctrl-a key acts as a
No.)
Yes – Port status is disabled.
Port Type
Possible Settings: E530, V.35, RS449, X.21
Default Setting: E530
Selects the synchronous data port type for the data port.
E530 – The port is an EIA-530A-compatible DCE. An EIA-530-compatible DTE can be
directly connected to the DB25 connector.
V.35 – The port is a V.35-compatible DCE. A V.35-compatible DTE can be connected to
the DB25 connector by using an MS34-to-DB25 adapter cable.
RS449 – The port is an RS449-compatible DCE. An RS449-compatible DTE can be
connected to the DB25 connector by using DB37-to-DB25 adapter cable.
X.21 – The port is a V.11/X.21-compatible DCE. A V.11/X.21-compatible DTE can be
connected to the DB25 connector by using a DB15-to-DB25 adapter cable.
Port Base Rate
Possible Settings: Nx64, Nx56
Default Setting: Nx64
Specifies the base rate for the synchronous data port. The data rate for the port is a
multiple (from 1 to 24) of the base rated specified by this configuration option.
Nx64 – The base rate for the port is 64 kbps. The data rate available for the port is
Nx64, where N is the number of channels to which the port is cross-connected (1–24).
Nx56 – The base rate for the port is 56 kbps. The data rate available for the port is
Nx56, where N is a number between 1 and 24.
