Change Address (cha)
(Disruptive)
Use the cha command to change the network address of a COMSPHERE 3400/4400 Series
modem, a COMSPHERE 3600 Series DSU or DBM, or a COMSPHERE 3800 Series DDD
modem. When this command is executed, the corresponding 6800 Series NMS device profile is
changed to reflect the update. Optionally, the device profiles of affected downstream/associated
devices can also be updated.
For most commands, NMS enables you to specify the destination for the command’s results and
schedule its execution. If the last page of the input form cannot accommodate the Destination for
results and Schedule execution fields, an additional page is provided. For a complete description
of these fields, refer to Chapter 1, Introduction.
Access Level:
Data Technician, Manager, System Administrator
Abbreviation:
cha
Restrictions:
The address of a carrier-mounted 3600 Series control DSU is determined
by its position in the carrier and cannot be changed by the user. For
3600 Series DSUs, the valid addressing range is from 1 through 79 (odd
addresses only). Even addresses are reserved for V.32 DBMs used for dial
backup. The network address of the DBM is created by adding 1 to the
network address of the DSU.
This command can be successfully executed only if the device profile
includes the correct serial number. Within a 10-second interval after
execution, this command can be canceled. After 10 seconds, the command
cannot be canceled. For COMSPHERE devices in DATAPHONE II mode,
this command can be sent only to locally connected control devices. We
recommend that you do not use this command to change the network
address of a 3800 Series tributary device since the status of this device will
always be reported as having a network address of 1.

Change Address Input Forms
When the cha command is selected, an initial input form is displayed that enables you to identify
the device. Different input forms are then displayed depending upon the device specified in the
initial input form. Input forms can be displayed for COMSPHERE devices operating in ADp
mode, and for (local control) COMSPHERE devices operating in DATAPHONE II mode.
