Criteria
Implementation Between ring/linear net-
works with ETHER-1000
restrictions
units (or mixture of ETHER-
1000 and ETHER-100
units).
If Ethernet traffic is to be tied
and added/dropped at the
same site, two ETHER-1000
(or two ETHER-100) units
are needed. In dual homing
applications, only one unit at
the tie site may be sufficient.
When tying between ring
and linear networks, ring
protection is lost.
Restrictions on maximum tie
cable length may be a
problem (see below).
When tying between optical
Tie Cable
units‟ CBW ports or between
ETHER-100 units, use 035-
86430-7X cable. Max tie
cable length depends on the
CBW port mode used for the
tie link. See optical unit
TPIM for more information.
When tying between
ETHER-1000 units, use 035-
86430-95 cable (20 inches).
