MCS-11 Repeater-to-Spur Daisy Chain Connection (J308/J309)
MCS-11 must be provisioned
MCS-11 J310 Master/Junction
to
enable XMT, RCV, and OUTPUT clocks. If an external modem is
being used, provision MCS-11 for
MCS-11 J310 Modem
. This selec-
tion disables XMT, RCV,OUTPUT clocks and all MCS-11 clocks
must now be provided by the external modem.
MCS-11 connector J308/J309 is typically used to connect a repeater to a spur or multi-
ple spurs in a daisy chain system configuration. Either repeater shelf 1 or repeater
shelf 2 may feed the spur shelf. The first connection out of the repeater must be cross-
wired from J308 to J308. Then, every shelf from the spur must be wired 1:1, J309 to
J308, in a daisy-chain fashion.
CROSSWIRED CABLE ASSEMBLY – Recommended connectorized cable assembly –
PN 695-7837-001 through -005 (26 AWG 8 pair shielded, jacketed cable with 15-pin
D-type connector on each end). See Figure A-14 for shelf connector J308 location and
pinout. See Figure A-14 for shelf connector J309 location and pinout.
DAISY CHAIN CABLE ASSEMBLY – Recommended connectorized cable assembly –
PN 695-7837-021 through -025 (26 AWG 8 pair shielded, jacketed cable with 15-pin
D-type connector on each end, wired 1:1).
