Chapter 1 Cisco ONS 15310-MA SDH Shelf Assembly Hardware
Cable Description and Installation
Note In ONS 15310-MA SDH OSP installations, E1/E3 ports are connected to the OSP. The OSP cabinet is
equipped with primary and secondary protections. In addition, isolation transformers are also provided.
RJ-45 cables: RJ-45 cables connect to the LAN, CRAFT, and UDC ports. An unshielded
twisted-pair (STP) #22 or #24 AWG wire is required for the CRAFT and UDC ports. Unshielded
twisted-pair is sufficient for the alarm and LAN(rear). 10/100-Mbps RJ-45 Ethernet STP (Shielded
Twisted Pair) cables are used to connect the CE-100T-8 and ML-100T-8 cards.
Alarm and timing (BITS) cables: The Alarm In port requires a shielded cable terminated with a
DB-37 connector; Alarm Out requires a shielded cable terminated with a DB-25 connector; and the
building integrated timing supply (BITS) ports require DB-9 connectors or a DB9BIT=BB9 to wire
wrap adapter.
1.8.2 Fiber Cable Installation
To install fiber-optic cables on the ONS 15310-MA SDH, a fiber cable with an LC connector must be
connected to an SFP. SFPs are installed in the SFP port on the ONS 15310-MA SDH. Each LC connector
contains the transmit (Tx) and receive (Rx) signal for that port. Cisco recommends that you label the
transmit and receive ports and the working and protection fibers at each end of the fiber span to avoid
confusion with cables that are similar in appearance.
You can route fiber cables through the optional fiber guide, installed at the bottom of the shelf assembly
(Figure 1-10).
