4.3.2 HD-10
The Total Access 3000/3010 High Density-10 U Interface (HD-10) is a high density
circuit card that provides the functionality of an entire ISDN channel bank deployed
across a T1 carrier facility. The HD-10 is designed to provide the maximum
concentration for 2B+D Basic Rate interface (BRI) ISDN in a compact configuration.
See Figure 11.
The HD-10 accepts up to ten "U" interfaces and multiplexes them for T1 transport.
Conversely, the HD-10 can also accept a T1 line carrying ten multiplexed "U"
interfaces and demultiplexes them for individual deployments. The Total Access 3000/
3010 HD-10 operates in the industry standard 3xDS0 mode and is compatible with any
compliant ISDN channel unit such as the ADTRAN D4 U-BR1TE. The HD-10 also
supports the ADTRAN proprietary 4:1 Time Division Multiplex (TDM) format. When
deployed in the 4:1 TDM mode, up to ten 2B+D BRI circuits can be delivered,
providing optimized utilization of the T1 carrier facilities.
