4.3.6.3. Optional Modems


Note: As optional modem, different types can be used for the Node AM: PHS8
(successor of HC25), PLS8 (for LTE), TRM-5, and MC88 modems. The layout
of all types is alike. In the following, the general term "modem" is shortly used,
referring to any of these types.
and PLS8. Modem type RV50X is supported but it is not available from
CommScope. It can only be ordered directly from the manufacturer.
A wireless modem is used to establish a remote connection to the Node AM. The
connection may be circuit switched or packet switched and is used to change the
parameters of the unit, check and clear alarms, or collect measurement and quality
statistics. Furthermore, the modem is requested at the Node AM to alert the operator
when there is an alarm.
The modem settings (i.e. which type of modem, Initstring, etc.) may only be changed
locally. Should a different modem be used, the operator should ensure that the settings
are changed prior to leaving the site.
For technical data of the individual modems, see chapter 7.5.1 HC25 / PHS8 / PLS8 /
MC88 / TRM-5. For the technical data of
manufacturer.
Initstrings
The initialization string (abbreviated by initstring) depends on the operator's network and
the modem. It may be necessary to adjust the initstring in the field.
When a modem is selected in the Node AM web interface the default initstring for this
modem is suggested. The initstrings for the different modems are listed in the software
description for the Node AM.
Modem Installed (valid for HC25 / PHS8 / PLS8 / MC88 / TRM-5)
The modem allows remote control and
maintenance of the Node AM.
Parameters may be changed; alarm and
measurement statistics
acknowledged and collected by the
OMC.
The modem is installed in the side tube
of the unit. To avoid a collision between
modem connectors
(especially with 4-way combiners), an
adapter kit for modem installation is
used (see chapters 5.2.2 and 8).
