PABX/PASTN calls

As a special feature, PABX interconnect to customers is available.

Trunked radios can connect to a mobile or fixed telephone network, and vice versa, through the PSTN Network. Both short-form and long-form access to as many as 24 PABX lines routed via 8 exchanges are provided for inbound and outbound traffic into the trunking network.

The interface to the PABX can be either E&M or loop disconnect, with both DTMF and 10 i.p.s. dialling.

Short-form PABX is available to any one of 4 different exchanges, although extension numbers are limited to 4 digits. To provide as much flexibility as possible, there is an interpretation table for the 4 combinations to produce any single BCD digit 0-9.

Long-form PABX allows for a maximum of 9 digits to be uploaded from the radio unit. The short-form PABX, routing table and short-form PABX digit stripping options may be configured.
