E1 Connectors on the PME1_21 and MSE1_16
The PME1_21 provides 21 balanced E1 tributary interfaces and the MSE1_16 provides 16 balanced E1
tributary interfaces through a SCSI-100 female connector. The SCSI-100 connector serves the 21 × E1
receive and transmit signals in the PME1_21 and the 16 x E1 receive and transmit signals in the MSE1_16.
I
MPORTANT
: The wiring of the SCSI-100 connector in both the PME1_21 and MSE1_16 is
identical. The different is that in the MSE1_16 only the first 16 E1s are used.
