3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET
Receive STS-3c Path – REI-P Error Count Register – Byte 3 (Address = 0x119C)
Receive STS-3c Path – REI_P Error Count Register – Byte 2 (Address = 0x119D)
Receive STS-3c Path – REI_P Error Count Register – Byte 1 (Address = 0x119E)
Receive STS-3c Path – REI_P Error Count Register – Byte 0 (Address = 0x119F)
Note:
Configuring the Receive STS-3c POH Processor block to increment the “Receive STS-3c Path – REI-P
Error Count” Register on a “per-STS-3c SPE” basis.
The user can configure the Receive STS-3c TOH Processor block to increment the “Receive STS-3c Path –
REI-P Error Count” Register, by the value “1” for each STS-3c SPE that contains a “non-zero” REI-P value.
The user can accomplish this by setting Bit 1 (REI-P Error Type), within the “Receive STS-3c Path – Control
Register – Byte 0” to “1” as illustrated below.
Receive STS-3c Path – Control Register – Byte 0 (Address = 0x1183)

The Receive STS-3c POH Processor block will increment these registers either by the number of erred STS-3c
SPE (e.g., STS-3c SPEs with a non-zero REI-P value) detected, or by the value of the REI-P value, within a
given STS-3c frame; depending upon user selection, as described below.
