With firmware version 5.0 (Option 42), the following new features are added to capabilities of the
ST2400A:
•
Payload bit error injection/ B3 Injection on the TX side (TSE)
•
B3, Path-REI, Payload bit error count measurement on the RX side (TSE ES, SES (SDH
only)
•
Alarm signal status (RX) - Path RDI, Loss of Pointer, Path AIS, Path REI
•
Path Overhead Monitor (RX) - Displays value of following bytes: J1, B3, C2, G1, F2, H4,
Z3/F3, Z4, N1
•
For the path overhead, C2 byte added at TX (Path Signal Label C2)) - Identifies High Order
Path Label Unequipped and High Order Path Label Mismatch. C2 byte can be set to any
value from 0x00 to 0xFF.
•
B3 Path Analysis/ J1 Path Trace (displayed as ASCII text).
•
Tx Patterns. PRBS 2-31
-1
and 2-31
-1
Inverted; Fixed (00 to FF) (TX mode button)
•
Pointers (Read-only menu under RX Trib button). Pointer Value displayed (0 to 782). Pointer
Measurement Counts for Positive Pointer Justifications, Negative Pointer Justifications, New
Data Flag (NDF)
•
Extended capability of View History button (more LEDs - virtual LEDs)
•
APS Switch Time measurement (LOF, LOS durations). APS testing can be performed by
causing protection switch via control of K1/K2 bytes and then displaying time to restore frame
synchronization. Highly-accurate LOF timer enables this test to be performed with
<1 ms resolution.
•
RX mapping (PRBS 2-23
-1
and 2-23
-1
Inverted; PRBS 2-31
-1
per ITU-T O.151 and 2-31
-1
Inverted per ITU-T O.181, User-defined byte 0x00 to 0xFF) (RX Channel Selection, under
RX Trib button)
NOTE:
Option 42 must be purchased for B3 capabilities (To determine if a TX board is B3
capable, the return value from the remote command "tx_brd_rev" must be greater than or equal to
35. To determine if an RX board is B3 capable, the return value from the remote command
"rx_brd_rev" must be greater than or equal to 9).
