interfaces will be displayed on the Port screen, among:
RS-232, V.35, RS-449,
X.21, T1
, and
E1
. (RS-449 and X.21 interfaces require an RS-422 LIC, which is
available by special order.) Note that a T1 or E1 LIC supports one port (port 4).
●
FRX6000 ports 0–7 on each RLP are determined by the Line Interface Card(s)
and attached cables. The RLP record identifies the LIC, and only the valid inter-
faces will be displayed on the Port screen, among:
RS-232, V.35, RS-449, RS-530,
X.21, T1
, and
E1
.
(RS-449, RS-530, and X.21 i
nterfaces require an RS-422 LIC.)
Note that a T1 or E1 LIC supports one port (port 0 or 4).
Blocked Port Flag
will cause the port to be enabled (
N
) or disabled (
Y
) at node IPL. The port will remain
in that state until this parameter is changed or an on-line enable (
[B], [B], [C]
from the
Main Menu) or disable (
[B], [B], [A]
from the Main Menu) is performed.
If set to
Y
, no backup DLCIs on this port will be used (even if the port is enabled via
on-line port enable).
Line Speed
is the data transmission rate in bits per second, and the clock speed on a non-T1/E1
serial port when the port is a physical DCE (i.e., the attached I/O cable is DCE). If this
port is a physical DTE, specify the line speed that matches (as closely as possible) that
of the device connected directly to the port.
Selecting this parameter for an FRX4000 DSU port will toggle between the two valid
values of
56K bps
and
64K Clear Channel
.
This parameter cannot be selected on a T1 or E1 port; rather, the line speed is deter-
mined by the port type and channel usage:
Full T1
1.344M
if
Base Channel Speed
is
56K
1.536M
if
Base Channel Speed
is
64K
Fractional T1
56K
per channel,
1.344M
max, if
Base Channel Speed
is
56K
64K
per channel,
1.536M
max, if
Base Channel Speed
is
64K
Full E1
1.920M
Fractional E1
64K
per channel,
1.920M
max
Selecting this parameter for any physical interface type except T1, E1, or FRX4000
DSU
will display a list of ranges. Press the letter corresponding to a range to display
the valid speeds within that range. All possible speeds are:
