DS21Q59 Quad E1 Transceiver
21 of 76
8.2 Framer Loopback
When CCR1.7 is set to 1, the DS21Q59 enters a framer loopback (FLB) mode (Figure 3-1). This loopback is useful
in testing and debugging applications. In FLB mode, the SCT loops data from the transmitter back to the receiver.
When FLB is enabled, the following occurs:
1) Data is transmitted as normal at TPOSO and TNEGO.
2) Data input through RPOSI and RNEGI is ignored.
3) The RCLK output is replaced with the TCLK input.

FUNCTION
ECUS
7
Error Counter Update Select. See Section 10 for details.
0 = update error counters once a second
1 = update error counters every 62.5ms (500 frames)
VCRFS
6
VCR Function Select. See Section 10 for details.
0 = count bipolar violations (BPVs)
1 = count code violations (CVs)
AAIS
5
Automatic AIS Generation
0 = disabled
1 = enabled
ARA
4
Automatic Remote Alarm Generation
0 = disabled
1 = enabled
RSERC
3
RSER Control
0 = allow RSER to output data as received under all conditions
1 = force RSER to 1 under loss-of-frame alignment conditions
LOTCMC
2
Loss-of-Transmit Clock Mux Control. Determines whether the transmit
formatter should switch to the ever present RCLK if the TCLK should fail to
transition.
0 = do not switch to RCLK if TCLK stops
1 = switch to RCLK if TCLK stops
RCLA
1
Receive Carrier Loss (RCL) Alternate Criteria
0 = RCL declared upon 255 consecutive 0s (125
ms)
1 = RCL declared upon 2048 consecutive 0s (1ms)
TCSS
0
Transmit Clock Source Select. This function allows the user to internally
select RCLK as the clock source for the transmit formatter.
0 = source of transmit clock is determined by CCR2.2 (LOTCMC)
1 = forces transmitter to internally switch to RCLK as source of transmit clock;
signal at TCLK pin is ignored
