10 Network Interfaces and Equipment
T1 Interfaces
When planning your networking requirements, one of the options you should
consider is multiplexing over Digital Services 1 (DS1) facilities. As the industry
standard for interconnecting digital systems, DS1 is an economical alternative to
analog trunking arrangements. Multiplexing up to 24 digitized voice/data
communications 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 ProLogix Solutions 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 channel-
bank-compatible interface.
