“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.
7
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). At a ring node or
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.

6
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).
7
SFP transceivers with copper ports are not supported.

The CBW port interface available on 86432-41 OC-3 JMUX unit offers Nx50 Mb/s
(N=1…4) of
bandwidth, the one available on 86417-0X OC-
12 JMUX unit offers Nx50 Mb/s (N=1…12) of
