The LDV5 and LDTPL signals are optional when using the ingress VTPP within
the TEMAP-84 which will regenerate the LDV5 and LDTPL signals from
LDC1J1V1, LDPL and the pointers within LDDATA[7:0]. In order to bypass the
ingress VTPP, the data on the Telecom drop bus must be locked such that all
three STS-1 SPEs are aligned to the STS-3 transport envelope with the J1 bytes
immediately following the C1 bytes. This is shown in Figure 54.
