Preliminary Information

14.0 Error Insertion
In T1 mode, six types of error conditions can be inserted into the transmit DS1 data stream through control bits,
which are located on page 1, address 19H - Error Insertion Word. These error events include the bipolar
violation errors (BPVE), CRC-6 errors (CRCE), Ft errors (FTE), Fs errors (FSE), payload (PERR) and a loss of
signal condition (LOSE). The LOSE function overrides the B8ZS encoding function.
In E1 mode, six types of error conditions can be inserted into the transmit PCM 30 data stream through control
bits, which are located on page 01H, address 19H. These error events include the bipolar violation errors
(BPVE), CRC-4 errors (CRCE), FAS errors (FASE), NFAS errors (NFSE), payload (PERR) and a loss of signal
error (LOSE). The LOSE function overrides the HDB3 encoding function.
15.0 Per Time Slot Control Words
There are two per time slot control pages (addresses AH and BH) (T1/E1) occupying a total of 24 unique
addresses in T1 mode or a total of 32 unique addresses in E1 mode. Each address controls a matching
timeslot on the 24 DS1 channels (T1) or 32 PCM-30 channels (E1) and the equivalent channel data on the
receive (DSTo) data. For example address 0 of the first per time slot control page contains program control for
transmit timeslot 0 and DSTo channel 0.
E1 Mode
15.1
Clear Channel Capability
In T1 mode, when bit zero (CC) in the per time slot control word is set no bit robbing for the purpose of
signaling will occur in this channel. This bit is not used in E1 mode.
15.2
Microport signaling
When bit one (RPSIG) is set, the transmit signaling for the addressed channel can only be programmed by
writing to the transmit signaling page (pages 5H and 6H) via the microport. If zero, the transmit signaling
information is constantly updated with the information from the equivalent channel on CSTi.
15.3
Per Time Slot Looping
Any channel or combination of channels may be looped from transmit (sourced from DSTi) to receive (output
on DSTo) STBUS channels. When bit four (LTSL) in the Per Time Slot Control Word is set the data from the
equivalent transmit timeslot is looped back onto the equivalent receive channel.
Any channel or combination of channels may be looped from receive (sourced from the line data) to transmit
(output onto the line) channels. When bit five (RTSL) in the Per Time Slot Control Word is set the data from the
equivalent receive timeslot is looped back onto the equivalent transmit channel.
Remote Timeslot Loopback and Local Timeslot should not be simultaneously activated in the same timeslot.
