FACILITY DESCRIPTION
Faktaansvarig - Subject responsible
CAPACITY
The capacity of TEs refers to the total capacity of
extensions in ASB 150 02, consisting of analogue
telephones, system telephones and ISDN terminals
( see document 1555 - ASB 150 02).
A maximum of 250 route numbers may be configured
in the system (including all individual and common
numbers).
Up to eight logical links may be connected to the
S-interface.
8 (4) S-interfaces per BTU-B_ board.
4 S-interfaces per MFU board
Max. 24 S-interfaces per system.
LIMITATIONS
The sum of analogue trunks, tie lines and number of
B-channels on digital trunks and S-interfaces is limited
to 120 individuals.
Only 2 TEs per ISDN link can be powered via the
ASB 150 02 ( see Installation Instructions).
No packet switching on the D-channel is supported.
Only incoming and outgoing calls can be handled by
ISDN telephones. No Inquiry call or transfer can be
done from these telephones.
Calling the S-interface, it is not possible to use the Call
back function.
Calling the S-interface, it is not possible to use the
Notify function on the OPERATOR console.
Intrusion is not accepted by the S-interface.
There is no possibility to use a S-interface as a
Diversion- or Follow me- address.
If an incoming ISDN call with a bearer service higher
then "speech" (i.e. "data") has been accepted by the
destination, no rerouting to a second destination is
allowed.
PROGRAMMING
The following commands are only accessible via
RASC:
HINT: The selected type of connection (T-interface or
S-interface) has to correspond to DIP switching
of the interface type on the BTU-B_/MFU board.
If the DIP switching does not correspond to the
selected type of interface, a warning will be
generated. (see Installation Instructions)
5401
Create route
This command is normally used to create a trunk
route.
In case of the S-Interface, the command is used for
defining the common directory numbers of the
interfaces as well as the MSN numbers of the
connected TEs.
3201
Route members
This command is used for defining the individual trunk
numbers, which are members of the route of the
common directory number for the S-interface as well
as the MSN numbers of the connected TEs.
3304
Alternative route choice 1
3306
Alternative route choice 2
These commands state the alternative routing of an
incoming call to an S-Interface or ISDN terminal in
case of busy. Two different alternative answer positions
may be programmed, which can only be another S-
Interface or another ISDN terminal from another S-
Interface.
