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
Used to connect switches to the public network or to other switches in a private network, DS1 also delivers
DEFINITY ECS offers several options in supporting the DS1 interface. The options include support for
■Uses
■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
