- Integrates
the tone generator, tone detection, system clock, and synchronization
functions onto one circuit pack for use in standard, high, and
critical reliability systems
- Provides
4 data links to the Time Division Multiplexing (TDM) bus and a
link through the memory bus to the processor
- Interfaces
the 3B2 MSA, DCS, ISDN, and Audix Interface service
- Allows
direct access to one data link from an EIA port on the circuit
pack
- Other
data links connect to a digital line circuit and a PDM or TDM
to access an MSA, DCS, CMS, ISDN, or Audix
- Data
links can connect to DS1 tie trunks to access DCS or ISDN applications
