Cascading Ether-1000 Units - GE JungleMUX SONET Technical Practice

Note: A maximum of 1 Gb/s Ethernet traffic can be passed between the ETHER-
1000 unit and its paddleboard in each direction.
Customer access ports are provided using either one or two quad-port plug-in
modules installed on the 86498-94 paddleboard. One ETHER-1000 quad-port
module and/or one ETHER-100 quad-port module can be equipped.
modules have dedicated locations (Banks A and B) on the 86498-94
paddleboard.
The ETHER-1000 quad-port module (86498-95) equipped with two 1000 Mb/s
(SFP) and two 100 Mb/s (SFP) Ethernet ports is currently the only module type
that can be installed into Bank B.
One of the following three ETHER-100 quad-port modules can be installed into
Bank A:
 86418-61 module with four 10/100 Mb/s (built-in RJ-45) Ethernet ports;
 86418-63 module with four optical 100 Mb/s (SFP) Ethernet ports;
 86418-64 module with two 10/100 Mb/s (built-in RJ-45) and two optical
100 Mb/s (SFP) Ethernet ports.

Cascading ETHER-1000 Units

A maximum of two ETHER-1000 units can be cascaded and connected to the
same CBW port on the JMUX units (Figure 3). This allows for:
more than 1 Gb/s of inter-bridge traffic to be added/dropped at a site (to a
-
maximum of 2 Gb/s in each direction);
providing more than 8 drop ports at a site (to a maximum of 16)
-
providing unit hardware redundancy without using additional CBW ports
-
and SONET bandwidth (see Path Protection below)
tying ETHER-1000 traffic between JungleMUX nodes using CBW tie
-
connections (addressed later in this section).
