Description
1
ALARM
O
Octet Timing Alarm
. When active, indicates loss of received bipolar violations that are used
for octet timing. Active high.
2
S+R
I
Positive AMI Data to Receiver.
Positive data from the XR-T6164 receive-side. Active low.
3
S-R
I
Negative AMI Data to Receiver.
Negative data from the XR-T6164 receive-side. Active low.
4
BLS
I
Byte Locking Supervision.
When active, causes blanking of PCMOUT under received
alarm conditions. Active low.
5
RX2MHz
I
Receiver 2.048MHz Clock
. Used to clock out PCM data.
6
BLANK
I
PCMOUT Data Blanking
. When active, forces PCMOUT data to all ones (AIS). Active high.
7
RXCKOUT
O
128kHz Extracted Clock.
Clock recovered from received data.
8
VDD
+5V
$10% Power Source.
9
RXCK2MHz
I
2.048MHz Clock.
Used by receiver clock recovery circuit.
10
TS1T
I
Transmitter Time-slot 1 Input
.
11
BDT
O
Transmitter Byte Deletion Flag
. Active when a transmit byte is deleted. Active high.
12
TS2T
I
Transmitter Time-slot 2 Input.
13
T+R
O
Transmit Positive AMI Data Output
. Data to XR-T6164 positive transmitter input. Active low.
14
T-R
O
Transmit Negative AMI Data Output.
Data to XR-T6164 negative transmitter input. Active
low.
15
TTSEL
I
Transmit Time-slot Select.
When high, pin 10 is selected; when low, pin 12 is selected.
16
ALARMIN
I
Alarm Input.
When active, inhibits insertion of violations used for octet timing in transmitter
output. Active high.
