3.3.5 Cables and connectors

The cable used to connect the PTP 300/500/600 Series Bridge PIDU Plus to the ODU can be any
standard CAT5e type provided that it is suitable for outdoor deployment. Motorola recommends
that cables to the specification below be used:

CAUTION: Failure to use the recommended (or equivalent) standard of cable may invalidate the
system's safety certification.
The cable used to connect the PTP 300/500/600 Series Bridge PIDU Plus to the users Network
Equipment can be any standard CAT5e Cable.
The PIDU Plus to ODU and the PIDU Plus to Network Equipment cables may be unscreened
(UTP) or screened (STP). However, unscreened cables reduce the system's ability to cope with
nearby lightning strikes. If lightning activity is common in the area of deployment, the use of
screened cable is highly recommended. See
The PIDU Plus provides screen continuity between the ODU and Network Equipment connections.
NOTE: The ODU network connection implements automatic MDI/MDI-X sensing and pair swap-
ping allowing connection to networking equipment that require cross-over cables (MDI-X networks)
or straight-through cables (MDI Networks).

3.3.6 PTP and Lightning Protection

The PTP 300 Series Bridge PIDU Plus meets the low level static discharge specifications iden-
tified in Section 17
Installations will generally require lightning or surge suppression to protect the customer indoor
equipment, a separate Ethernet surge suppressor must be used and appropriately earthed. Suit-
able surge suppressors can be sourced from your Motorola Point-to-Point Distributor or Solutions
Provider. See Section 11

3.3.7 Mounting Brackets

The PTP 300 Series Bridge is supplied with a mounting bracket suitable for mounting the ODU
to a pole of 50mm (2") to 75mm (3") in diameter. For more details on mounting, see
"Installation".
The bracket allows for adjustment in both azimuth and elevation. The bracket may be split
allowing the pole mount section of the bracket to be mounted to the pole first. This allows the
installer to take the weight of the unit and secure it, one handed, with a single mounting bolt.
The PIDU Plus can either be desk or wall mounted. The preference is wall mounted with the
cables dressed to a cable channel. Wall mounting is achieved by screwing through the mounting
