Hicom 102-Technical Specifications/ Installation and Start-up Instructions
5. Important Notes
5.1
Placing
in
Service
Modification of customer data can only be done at the express
wish of the customer and only at a fee.
5.2
Exchange Lines
-
The exchange feeding voltage must be at least 48 V, otherwise
serious functional disturbances may result.
-
The presence of an exchange line is automatically detected by
the Hicom 102 after the AC power is connected. For this reason
after connecting an exchange line, the system must be briefly
switched off.

Outward Restriction of Trunk Access
B y deletion of a user in the line assignment, he can be given
outward restriction of trunk access, i.e. he can set up no outside
calls.
5.4
Printer Connection
Attention:
The printer connection, for which provision is made, is nor being
supplied at present.
5.4.1
Interface Data
-
Interface via RS 232 C (V.24)
-
Port speed 4800 bit/s
-
interface allocation
5.4.2
Printer functions
-
Automatic printout of the following data at end of call (only
for outgoing calls)
•
calling party's call number
•
external call number
•
call duration
-
Printout of the current system programming
•
printout follows selection of code 19998 on the master
station
5.5
Suppression of Gaps in the Feeding Current
In certain cases due to interruptions in the feeding current after
exchange seizure, the terminal functions may be affected, e.g.
discontinuation of dialing after exchange seizure or obtaining of
wrong numbers.
In these cases the feeding current gaps can be bridged for
individual users or for all users (for procedures see 4.4
"Interpretation of exchange tone")
In this case, however, exchange seizure is generally performed
with
a
delay.
5.6
Connection of Second Ringers
If additional second ringers or telephones are connected (e.g. via
AWADO) there may be problems with the ringing signal voltage.
It must be ensured, that not more than six ringers sound
simultaneously.
(Usual ringer impedance: approx. 7k ohms)
