Procedure
Installer Check
ü
The HMU DCE should be connected to the DTE port of the local maintenance terminal. If
the connection to the HMU requires a DTE-to-DTE or DCE-to-DCE interface, see the HMU
user manual for information about null modem adapters. The HMU user manual also
provides information about remote terminal connections and X.25.
1
Connect a standard 9-pin, terminal cable to the HMU front panel craft (DB-9) port or connect a 25-pin
terminal cable to the OS port (J30) on any of the shelves in the network. If you are connecting the
maintenance terminal to the OS port (local RS232 or remote X.25), a null modem adapter is required.
The craft port is configured as DCE. The OS port is configured as DTE.
