Transmission characteristics

Engineering and configuration guidelines
The integrated voice and data can use a single medium to transmit speech and
data between locations.
There are three advantages to T1 or E1 compatibility:
• E-link or T-link version 2 supports Meridian 1 to Meridian 1,
Meridian 1 to SL-100, and Meridian 1 to Custom DMS-100 for 56 or 64
kbps data, ad Meridian 1 to Central Office connectivity.
• includes capability to be configured as a standard T1 DS-1 link
• eliminates need for channel bank equipment when using digital network
facilities
PRI utilizes Nortel Network's T-link Data Rate Adaptation protocol. There
are three transmission modes:
• asynchronous 50 bps to 19.2 kbps
• synchronous 1200 bps to 64 kbps
• half or full duplex
There are five types of transmission necessary for ISDN compatibility:
• carrier system compatibility
• synchronization
• signaling
• trunk types supported
• voice transmission
These transmission types are described in the lists that follow.
Carrier system compatibility:
• compatible with D2, D3, D4, B8ZS, and Extended superframe format
(ESF) framing on T1 repeater cables
• compatible with systems that use a DS-1 interface, such as fiber optics,
microwave, copper, satellite, and infrared
