Digital Interfaces

Lucent Technologies supports both T1 and E1 facilities. As industry standards around the world, T1 and E1 facilities provide the latest alternative to analog trunking.

E1 Interface

DEFINITY ECS also supports E1 connections. T1/E1 access and conversion allows simultaneous connection to both T1 (1.544 Mbps) and E1 (2.048 Mbps) facilities (using separate circuit packs).

T1 Interfaces

When planning your networking requirements, one of the options you should con- sider is multiplexing over Digital Services 1 (DS1) facilities. As the industry stan- dard for interconnecting digital systems, DS1 is an economic alternative to analog trunking arrangements. Multiplexing up to 24 digitized voice/data com- munications paths onto a single T1 carrier or other high-speed digital facility (such as fibre or microwave) can reduce your network trunking and equipment costs.

Used to connect switches to the public network or to other switches in a private network, DS1 also delivers high-speed, end-to-end digital connectivity. Voice and data calls are completed at transmission speeds of up to 64 kbps.

DEFINITY ECS offers several options in supporting the DS1 interface. The options include support for voice-grade DS1, alternate voice/data, and Digital Multiplexed Interface. The voice-grade DS1 interface is a T1 D4 chan- nel-bank-compatible interface that does the following:

■Uses in-band bit-robbed signaling to provide 24 voice-grade-only tie trunks consisting of 56-kbps channels for voice and voice-grade data transmission

■Interconnects DEFINITY ECS with other switches with an external D4 channel bank or with other switches (analog or digital) having the appropriate interfaces

■Interconnects DEFINITY ECS with central offices such as Lucent Technologies 4ESS switch (where services such as MEGACOM and Software Defined Network can be accessed) and 5ESS switches

■Interconnects DEFINITY ECS with private networks by connection with DS1 facilities

■Can be used with the same Automatic Alternate Routing capabilities as normal analog E & M lead tie trunks
