Type
Description
Frame Format Select selects the transmit TDM Port Frame type (only valid if
SFS = 1).
Multiframe Format Select selects the transmit TDM Port CAS multi-frame type
(only valid if SFS = 1).
Buffer Frame/Fragment Depth selects the number of 125 us periods of TDM
data internally buffered by the S132 for the CES/SAT engines (see PTCR1.BPF).
The number of bytes specified by BFD * BPF must be ≤ B.BCDR1.PMS for all
RXP Bundles assigned to this TDM Port.
Bytes Per Frame/Fragment = # bytes transmitted from TDM Port during a 125 us
period (125 us = time period for 1 CES Frame or 1 SAT Fragment). For T1, BPF =
23 (0x17; SAT/CES). For E1, BPF = 31 (0x1F; SAT/CES).
Decap Priority selects the RXP (Decap) SAT/CES/HDLC processing priority
Disable Overwrite Signaling On TDAT = “1” disables the S132 from over-writing
CAS codes in the transmit TDM Port TDAT pin, T1/E1 CAS code positions (T1
robbed-bit signaling and E1 Timeslot 16). When DOSOT = 0, the S132 over-writes
those TDAT time positions. DOSOT does not affect the transmit TDM Port TSIG
data (when a TDM Port is programmed to transmit CAS the CAS codes are
transmitted on TSIG regardless of the DOSOT setting).
Reserved.
Port Transmit Configuration Register 2. Default: 00.00.00.08h
Reserved.
Port Receive to Port Transmit Line Loopback = “1” enables the TDM Port Line
Loopback from RDAT, RSYNC, RSIG to TDAT, TSYNC, TSIG respectively. The
transmit timing is not automatically changed when PRPTLL = 1. Pn.PTCR2.TSS
must be programmed so the incoming RDAT data stream timing is used to time
TCLKO and RCLK. PRPTLL = 1 over-rides Pn.PTCR2.TDS forcing TSYNC to be
an output.
Transmit Input Output Enable.
Transmit Clock Enable.
Transmit Frame Timing Synchronized to RSYNC.
1 = T1 frame structure
1 = E1 multiframe structure (16 frame multiframe structure)
3 = T1 – ESF multiframe structure (24 frame multiframe structure)
3 = 4 Frame/Fragments per staging buffer (500 us staging buffer)
31 = 32 bytes per 125 us period
1 = high priority
1 = TDAT/TSYNC/TSIG loopback data from receive inputs RDAT/RSYNC/RSIG
1 = TDAT/TSIG/TSYNC enabled (Pn.PTCR2.TDS selects TSYNC direction)
1 = TCLKO enabled with timing source selected by Pn.PTCR2.TSS
1 = Transmit Frame Timing synchronized to TSYNC input (when TDS = 0)
0 = E1 frame structure
0 = No multiframe structure
2 = T1 - SF multiframe structure (12 frame multiframe structure)
0 = Disable SAT/CES data path for transmit TDM Port
1 = 1 Frame/Fragment per staging buffer (125 us staging buffer)
2 = 2 Frame/Fragments per staging buffer (250 us staging buffer)
0 = low priority (processed after all high priority data has been completed)
0 = TDAT/TSYNC/TSIG pass data from RXP packets (normal)
0 = TDAT/TSIG/TSYNC disabled (high-impedance)
0 = TCLKO disabled (high-impedance)
0 = Transmit Frame Timing synchronized to RSYNC input
0 = 1 byte per 125 us period
