COMSPHERE 3000 Series Carrier
3-6 March 2001 3000-A2-GA31-F0
T1 COM Port Connection to an
External PC
Communication between the T1 CSUs and
T1 DSU/CSUs in a 3000 Series Carrier and an external
PC occurs through a shared communication (COM) port.
The PC can be attached locally or through an external
modem.
• T1 CSUs and T1 DSU/CSUs do not have their own
COM port for external access. One of the
T1 devices in the carrier must be selected as the
master communication port.
• The selected T1 device provides the COM port for
all the T1 CSUs and T1 DSU/CSUs in the carrier.
• The T1 device is configured, via COM port
configuration options, so that Port 2 on the
T1 auxiliary backplane is the COM port for the
carrier.
• Using the front panel emulation (FPE) diskette, the
attached PC can then access any device in that
carrier through the shared COM port on the master
communication unit.
The figure below shows the COM port adapter.
