OSC |
Uses the on-board oscillator as a reference. |
|
A_CLOCK |
Causes the board to act as a clock slave to the H.100 bus A clock by deriving the local clock from the bus. Another H.100 board (or H.110 board) must drive the clock on the bus. |
|
B_CLOCK |
Causes the board to act as a clock slave to the H.100 bus B clock by deriving the local clock from the bus. Another H.100 board (or H.110 board) must drive the clock on the bus. |
|
NETWORK |
Causes the board to derive the local clock, telephony bus clock, and line transmit clock using the clock extracted from one of the BRI trunks. |
|
NETREF |
H.100 network reference. |
