Connectivity - GE JungleMUX SONET Technical Practice

 Forced to priority n (n=0, 1...6).
 "Around the ring" latency monitoring (for highest priority frames)
 4 or 8 ports on the paddleboard (max 2 are Gigabit Ethernet)
 Quad-port modules with copper (RJ-45) ports and/or SFP cages connect to
the base paddleboard.
o Copper ports support:
 10/100Base-TX Ethernet connections
 Half and full duplex operation
 Full auto-negotiation for speed and duplex mode with local
LAN devices.
o 1-Gbps SFP cages can accommodate either 1000Base-LX or
1000Base-SX optical transceivers with DMI interface.
o 100-Mbps SFP cages can accommodate either 100Base-FX or
100Base-LH optical transceivers with DMI interface.
 Supports cascaded ETHER-1000 configuration to provide up to 16 access
ports.
 Backwards compatible with ETHER-100 unit.
 Per-port ingress and egress rate limiting.
o Available rate limits range from 128 kb/s to 800 Mb/s
o Up to three independent per-port user-configurable ingress rate
limiting policies that may be set to apply to broadcast, multicast,
and/or unicast frames with specific source priorities.
 Port mirroring
 Firmware upgrades through CI.

Connectivity

The unit performs a bridging function between the GMII port (interface to the
paddleboard) and its two (left and right) Line ports. The Line ports connect to
OC-3/OC-12/OC-48 JMUX unit's CBW ports (Figure 2).
add/drop node in a linear network, the left and right Line ports are connected to
the left and right JMUX units, respectively, to allow bridging to/from both left and
right fiber pairs. Table 1 shows the bandwidth available for bridging through the
Line port depending on the type of optical aggregate unit used.
Forcing the access port‟s Mapping Priority also forces the port‟s Default Priority, which is then

applied to all frames ingressing the port (except to frames matching the selected EtherType).

SFP transceivers with copper ports are not supported.
