Function
Outgoing C1 Frame Pulse (OC1FP). This signal indicates the first
C1 octet on the outgoing SBI or TelecomBus.
In SBI336 mode:
This signal also indicates multiframe alignment which occurs every
4 frames, therefore this signal is pulsed every fourth C1 octet to
produce a 2 KHz multiframe signal.
When using the SBI bus in synchronous mode the OC1FP signal
indicates T1 and E1 signaling multiframe alignment by pulsing on
48 SBI frame boundaries. This must be done if CAS is to be
switched along with the data.
In TelecomBus mode:
This signal may also be pulsed to indicate the J1 byte position and
the byte following J1. The J1 byte position is locked to an offset of
either 0 or 522. The byte following J1 is used to indicate
multiframe alignment and is only pulsed once every 4 frames
marking the frame with the V1s.
OC1FP is updated on the rising edge of SREFCLK.
Outgoing Data (ODATA[7:0]). The Outgoing Data buse,
ODATA[7:0], is a time division multiplexed buses which transport
tributaries by assigning them to fixed octets within the SBI or
TelecomBus structure.
ODATA[7:0] are updated on the rising edge of SREFCLK.
Outgoing Bus Data Parity (ODP). The outgoing data parity signal
carries the even or odd parity for the outgoing bus. In SBI336
modes, the parity calculation for ODP encompasses the
ODATA[7:0], OPL and OV5 signals. In TelecomBus mode, the
parity calculation encompasses the ODATA[7:0] and optionally the
OC1FP and OPL signals.
ODP is updated on the rising edge of SREFCLK.
