Making an outgoing call
Overlap sending
You can seize a port by dialling the port number (e.g. 701). When you see SETUP ACK dis-
played on your keyset, you can dial the destination number.
Enblock sending
You can make a call through the enblock sending mode port by dialling the port number
and the destination number followed by #.
Incoming call routing
This depends on the mode of BRI/PRI set by MMC 419/420. See Table 6.

BRI LT-S Mode
Note: All of the following examples are valid only after programming with the appropriate MMC. Refer
to Part 4 of this manual.
Making a call from a DCS subscriber (DGP/SLT) to an ISDN terminal attached to LT-S port
To call a terminal attached to an LT-S port, dial the MSN of the terminal. If a terminal with
MSN of 7803 is attached to 703, and you dialled 7803, a SETUP message will be sent out
through 703 with calling party number of 7803. All terminals with MSN of 7803 will alert.
Alternatively, to call a terminal (or terminals), dial the port number. This time the calling
party number of the SETUP message is vacant. All the terminals attached to that port will
alert, with no regard to MSN number.
In the above cases, dial is always sent in enblock mode.
Caution
When making a call from an S0 terminal, take care with the CLI number. It is usually sent when
the call is made, and if that number is not registered in MMC 424 the system will disconnect
the call.
Making a call from a terminal attached to LT-S port to a DCS subscriber (DGP/SLT)
To call a DCS subscriber from an ISDN terminal, dial the number you want to call. It is of no
concern to the BRI card whether the terminal sends the number in enblock or overlap
mode.
Making a call from a terminal attached to LT-S port to a remote terminal through a TRK
Dial the TRK number followed by the destination number. ISDN TRK and analogue TRK op-
erate in the same way as seen from a terminal. When calling through an ISDN TRK there
