RFPO1

Output

AA12

The Receive Frame Pulse Output (RFPO), when the

RFPO2

 

AB12

framing alignment is found (the OOF register bit is

RFPO3

 

AC13

logic zero), is an 8 kHz signal derived from the

RFPO4

 

AB13

receive line clock. RFPO pulses high for one RCLK

 

 

 

cycle every 2430 RCLK cycles (STS-3c (STM-1)).

 

 

 

RFPO is updated on the rising edge of RCLK.

 

 

 

This pin is available independently for each channel.

 

 

 

 

RALRM1

Output

AA14

The Receive Alarm (RALRM) output indicates the

RALRM2

 

AC15

state of the receive framing. RALRM is low if no

RALRM3

 

Y14

receive alarms are active. RALRM is high if line AIS

RALRM4

 

AB15

(LAIS), path AIS (PAIS), line RDI (LRDI), path RDI

 

 

 

(PRDI), enhanced path RDI (PERDI), loss of signal

 

 

 

(LOS), loss of frame (LOF), out of frame (OOF),

 

 

 

loss of pointer (LOP), loss of cell delineation (LCD),

 

 

 

signal fail BER (SFBER), signal degrade BER

 

 

 

(SDBER), or path signal label mismatch (PSLM) is

 

 

 

detected in the associated channel. Each alarm can

 

 

 

be individually enabled using bits in the S/UNI-

 

 

 

QUAD Channel Alarm Control registers #1 and #2.

 

 

 

RALRM is updated on the rising edge of RCLK.

 

 

 

This pin is available independently for each channel.

 

 

 

 

TXD1+

Differential

The transmit differential data outputs (TXD+, TXD-)
