ODU/HSS Unit Connection Pinout

Condition 2: Total HSS Cable Length

The total path of the HSS sync pulse must not exceed 300m. This applies no matter how
many HSS units are used. To illustrate the method for calculating the sync pulse path length
we show three examples. For our purpose, let:
L denote the length of the ODU-HSS unit cable at SYNC n on HSS unit m
mn
H be the length of the cable joining HSS unit m to HSS unit m+1
m
One HSS unit with five collocated ODUs
PathLength = L

Two cascaded HSS units as shown in
PathLength = L

Radio Frame Pattern (RFP)

A Radio Frame Pattern (RFP) is the cycle duration of transmit and receive of the air-frame.

Without HSS

When selecting Ethernet services, the system automatically and transparently chooses the
optimal RFP.
