Preliminary Data Sheet
May 2001
21 28-Channel Framer Block Functional Description
21.14 Transmit Signaling Per-Link Feature Provisioning
The transmit signaling processor requires the provisioning of four items for each link to enable signaling extraction
and delivery.
21.14.1 Signaling State Mode Source Selection
The signaling state mode source is selected by programming FRM_T_FGSRC in FRM_TSLR32, Transmit Signal-
ing Link Register 32 (R/W),
ming the state mode. If so, the host will have to program the state mode for all of the time slots on each link.
