5.5.4 Installing the VDH2(8)-U( )
The 10Base-T ports on the VDH2(8)-U( ) ETU use
4-wire polar cables.
When connecting a VDH2(8)-U( ) ETU to a Multiline
Terminal, avoid using under-carpet cables because
the device becomes susceptible to outside noises. It
is better to use EIA/TIA round cables instead of flat
cables. When under-carpet cables are used, you
must follow the installation instructions provided by
the cable manufacturer. Also consider these
precautions:
Limit the under-carpet cable length to 65 feet.
When using multiple pair cabling to connect
the VDH2(8)-U( ) units to the multiline terminal,
do not include analog lines in the same cable.
When connecting a VDH2(8)-U( ) ETU, use the
FCE-U10 Unit for proper wiring. Lead the cable
connected to the ETUs out through the clamp on the
KSU as shown in Figure 5-50 Front Cover Extender
for VDH2(8)-U( ) ETUs. Refer to 3.3 Installing a
Front Cover Extender (FCE-U10 Unit) in Chapter 4
on page 4-13.
A maximum of 9 VDH2(8)-U( ) ETUs can be
installed in Slots S1~S8 in any system KSU.
