Having the radio overhead multiplexed together into a standard T1
also allows the overhead to be transported over non-Alcatel radio facil
-
ities (i.e., channel banks, fiber optic terminals, or no-Alcatel radio
equipment). This feature is extremely useful in SONET rings where
part of the ring will be MDR-8000s OC3 radio and part will be SONET
fiber equipment.
3.5.4 MDR-8000 Synchronous Repeater Compatibility Matrix
Table 3 - 1 lists the combinations of MDR-8000 capacities that support the use of the syn-
chronous repeater cable.
3.5.5 MDR-8000 Synchronous Repeater Cables
Refer to Table 3 - 2.
Notes:
1 For both High and Low capacity applications, refer to drawing number
3DH031770000EJZZA for the specific cable connections.
2 The MDR-8000 Synchronous Repeater Cable part number is the same for both
the DS1 and D3 versions of the radio. Refer to drawing number
3DH031770000BJZZA for cable dash numbers and lengths.
