Support for T1 Switched 56

Digital Data Transmission

For Hybrid/PBX and Key mode systems, Release 4.0 expands support of T1 functionality by providing access to digital data over the public switched 56-kbps network, as well as to digital data tie-trunk services. Users who have T1 facilities for voice services can now use them for video or data calls at rates of 56 kbps per channel (112 kbps for video calls using 2B data). The Release 4.0 offering also includes point-to-point connectivity over T1 tie trunks, allowing customers to connect two MERLIN LEGEND Communications Systems or a MERLIN LEGEND Communications System with a Lucent Technologies DEFINITY®G1.1 Communications System or DEFINITY Enterprise Communications Server. The two communications systems can be co-located or at different sites.

Forwarding Delay Option

Each user can program a Forwarding Delay setting for the Forward, Remote Call Forwarding, or Follow Me features. The forwarding delay is the number of times that a call rings at the forwarding extension before the call is sent to the receiver. The delay period gives the original call recipient time to answer or to screen calls by checking the displayed calling number (if available). The delay can be set at 0 up to 9 rings. The factory setting for the forwarding delay is 0 rings (no delay).

Voice Announce on Queued Call Console

The system manager can enable the fifth Call button on a QCC console (Hybrid/PBX mode only) to announce a call on another user’s speakerphone (providing the destination telephone has a voice announce-capable SA button available). A QCC cannot receive voice-announced calls; they are received as ringing calls. The factory-set status for the fifth Call button is Voice Announce disabled.
