8. CIRCUIT OPERATION

8.1. IC14(ASIC)

- EC bus interface

Independent bus for 16bit/8MHz two-way address data multiplex.

- CT bus interface

Supports eight 8.192MHz highways (128 time slots).

- Local TSW

Exchanges the time slots between CT bus (1024ch) and local
highway (64ch).

- Local highway Interface

Holds 2.048, 4.096, 8.192MHz highway (Up to 64 time slots) (VOX
bus onboard)A stream 0 through 15 (1 stream = 128 time slots) of
PCM data can be switched to a local highway (64time slots). See
the figure blow for the examples of the local highway time slot
configurations (You can assign desired slots.).
