The following section describes the telephone line and modem requirements for the
Hardware Management Console Remote Support Facility (RSF).
It is the customer's responsibility to arrange for installation and all costs of
common-carrier equipment.
Each Hardware Management Console (HMC) comes with a modem. One telephone
line is required for each modem installed.
Note: It is recommended that CPCs be assigned to more than one Hardware
Management Console phone server.
When ordering telecommunications service, be prepared to identify the following:
v The type of telephone jack required (country dependent)
v The long distance carrier
v The selection of either dual tone multi-frequency (DTMF) or rotary (pulse) to be
installed
v Installer of the telephone wiring and jack
The telephone line must be a dial-up (public switched network) analog type* with
24-hour, 7-day-a-week availability.
Note: *Digital telephone lines must not be used.
All models require a modem for telephone-based RSF. The modem supplied by
manufacturing is dependent on the destination country homologation requirements.
Many geographies will receive an internal modem (Machine Type 5634) with a
Hardware Management Console FC 0090, while some countries will continue to
receive an external modem. The general specifications of the supported modems
(33K bps and 56K bps models) are:
v Data rate:
– v34 - 36K bps and below
– v90 - 56K bps and below
v Tone or pulse dialing
v Standards:
– v34 - 36K bps:
- Data: v.34, v.32bis, v.22bis4
- Error correction: v.42
- Data compression: v.42 Class 5; v.42bis
