Feature Descriptions
(continued)
I
Signaling:

16-state per-channel robbed bit.
— DS1: D4 superframe 2-state and 4-state per-
channel robbed bit.
— DS1: SLC-96 superframe 2-state, 4-state, 9-state,
and 16-state per-channel robbed bit.
— DS1: channel-24 message-oriented signaling.
— ITU CEPT: channel associated signaling (CAS).
— Transparent (all data channels).
I
Alarm reporting, performance monitoring, and main-
tenance:
— ANSIT1.403-1995, AT&T TR 54016, and ITU
G.826 standard error checking.
— Error and status counters.
— Bipolar violations.
— Errored frame alignment signals.
— Errored CRC checksum block.
— CEPT: received E bit = 0.
— Errored, severely errored, and unavailable sec-
onds.
— Selectable errored event monitoring for errored
and severely errored seconds processing with
programmable thresholds for errored and severely
errored second monitoring.
— CEPT: Selectable automatic transmission of E bit
to the line.
— CEPT: Sa6 coded remote end CRC-4 error E bit =
0 events.
— Programmable automatic and on-demand alarm
transmission.
1. Automatic transmission of remote frame alarm
to the line while in loss of frame alignment
state.
2. Automatic transmission of alarm indication sig-
nal (AIS) to the system while in loss of frame
alignment state.
— Multiple loopback modes.
— Optional automatic line and payload loopback
activate and deactivate modes.
— CEPT nailed-up connect loopback and CEPT
nailed-up broadcast transmission TS-X in TS-0
transmit mode.
— Selectable test patterns for line transmission.
— Detection of framed and unframed pseudorandom
and quasi-random test patterns.
— Programmable squelch and idle codes.
I
System interface:
— Autonomous transmit and receive system inter-
faces.
— Independent transmit and receive frame synchro-
nization input signals.
— Independent transmit and receive system inter-
face clock.
— 2.048 Mbits/s, 2.048 MHz concentration highway
interface (CHI) default mode.
— Optional 4.096 Mbits/s and 8.192 Mbits/s data
rates.
— Optional 4.096 MHz, 8.192 MHz, and 16.384 MHz
frequency system clock.
— Programmable clock edge for latching frame syn-
chronization signals.
— Programmable clock edge for latching transmit
and receive data.
— Programmable bit and byte offset.
— Programmable CHI master mode for the genera-
tion of the transmit CHI FS from internal logic with
timing derived from the receive line clock signal.
I
Digital phase comparator for clock generation in the
receive and transmit paths.
