B Side Drop Bus Channel n Current One Second BIP-2 Counter - Low
Order Byte: This counter holds the lower 8 bits of a 16 bit counter for BIP-2
counts that occurred in the current one second interval. This location is
updated from the B side current one second BIP-2 counter at one second
intervals.
B Side Drop Bus Channel n Current One Second BIP-2 Counter - High
Order Byte: This counter holds the higher 8 bits of a 16 bit counter for
BIP-2 counts that occurred in the current one second interval. This location
is updated from the B side current one second BIP-2 counter at one second
intervals.
B Side Drop Bus Channel n J2 and N2 Byte Message Segments: The
following locations store the B side drop bus 64-byte J2 message when
control bit BnJ2S1 is a 1, and 16-byte J2 and N2 drop and microprocessor
written comparison messages when control bit BnJ2S1 is a 0. The following
list the location of the drop message segments and the microprocessor writ-
ten segments.

B Side Drop Bus Channel n V1 Byte: This register is updated every 500
microseconds. This location stores the B side drop bus V1 byte pointer byte
for the VT/TU selected. Bit 7 in this register corresponds to bit 1 in the V1
byte.
B Side Drop Bus Channel n V2 Byte: This register is updated every 500
microseconds. This location stores the B side drop bus V2 byte pointer byte
for the VT/TU selected. Bit 7 in this register corresponds to bit 1 in the V2
byte.
B Side Drop Bus Channel n V4 Byte: This register is updated every 500
microseconds. This location stores the B side drop bus V4 byte for the
VT/TU selected. Bit 7 in this register corresponds to bit 1 in the V4 byte.
B Side Drop Bus Channel n V5 Overhead Byte: This register is updated
every 500 microseconds. This location stores the B side drop bus V5 over-
head byte for the VT/TU selected. Bit 7 in this register corresponds to bit 1
in the V5 byte.
