Shipped with all purchased JungleMUX nodes is a Node Assignment Drawing
(NAD), which provides necessary configuration details for the units and shelf
location.
Product Color and Nomenclature
The product line has undergone a transition to a new colored package. To
distinguish between legacy gray and new black, a "B" prefix is added to all black
shelf and unit code numbers to identify the item color. Note that there is no
difference in the internal electronics and therefore the functioning of this
equipment, whether it be gray or black. Gray-colored modules were discontinued
in June 2008. The modules added to the product portfolio after November 2007
have been available in black only. To simplify the information within this TPIM,
all unit code numbers will be stated without any color prefix. The ordering
information (Section 8), however, does include the available color options.

2. UNIT OVERVIEW
A JungleMUX SONET system provides a mechanism to transport various forms
of electronic data over an optical fiber. One application is to provide a bridging
function between two or more Ethernet/IEEE 802.3 LAN that are physically
separate. The 86498 ETHER-1000 unit addresses the applications where it is
required to provide more than 300 Mb/s of capacity between LANs, or the
applications where the extended set of features offered by this unit is the
imperative (refer to 86418 ETHER-100 and 86438 ETHER-10 Unit Technical
Practice and Installation Manuals for comparison). The unit acts as an intelligent
learning bridge, forwarding to other units only those frames that are not locally
addressed.
Summary of Features
1
IEEE 802.3 compatible Ethernet
interfaces for direct attachment to
10/100/1000 Mb/s Ethernet LANs.
Use of 1 to 24 STS-1 SPEs for inter-
bridge data transport (50 to 1200 Mb/s).
Bandwidth partitioning into multiple (up
to 4) independent TDM streams (TDM
pipes) where individual stream‟s
bandwidth can range from 1 to 24 STS-
1 SPEs.
Supports point-to-point, linear and ring
network topologies. Each TDM stream
can be configured into an independent
network topology with one or more
remote ETHER-1000 and/or ETHER-
100 units. Traffic can be passed
between contiguous networks (at
collocated nodes).
Provides rapid path switching after a fiber or JMUX unit failure in ring
applications (typically within 5 ms).
1
For ETHER-1000 firmware versions <3.00, some features are either not supported or supported
in a limited fashion.

Supports VLANs
oAbility to share the allocated STS-1 SPE(s) between multiple sets of
bridged LANs. Privacy is maintained between the different sets.
oSupports up to 60 „Distributed Port-based‟ VLANs (D-PVLAN) for
guaranteed isolation of traffic between ports with different D-PVLAN
membership assignments. D-PVLANs are pre-assigned to the four
TDM pipes in sets of 15. Each provisioned Ethernet access port
requires a D-PVLAN assignment (1-60).
oSupports D-PVLAN trunking (ability to assign multiple D-PVLAN
memberships to a port). On a D-PVLAN trunk, all frames are
802.1Q tagged to distinguish between different D-PVLANs.
oAllows transparent transport of Ethernet frames with 802.1p and
802.1Q VLAN tags including frames with “QinQ” nested (stacked)
802.1Q tags (up to 28 levels of “QinQ” nesting; max frame length is
1632 bytes).
oOptional QVLAN filtering (per port)
Supports all 4000 802.1Q VLANs, with up to 50 user-
configurable QVLAN memberships per port.
Applied to both ingress (input) and egress (output) frames.
Configurable per-QVLAN output tagging (available when QVLAN filtering is
enabled). Allows for adding ("pushing") a tag to untagged frames or
removing ("popping") the outer
2
tag from tagged frames at egress.
Powerful MAC address management
oA 32,768-entry MAC address table in the ETHER-1000 unit (“WAN”
switch).
oBuilt-in 8-port Ethernet Layer-2 switch on the base paddleboard
(“LAN” switch) with 8192-entry MAC address table.
oUser-configurable aging time for learned MAC addresses (ranging
from 30 seconds to 1 hour, or never).
oConfigurable static (not aged) MAC addresses, 20 per port, stored in
flash.
oMAC address learning and sorting per D-PVLAN and QVLAN allows
for independent routing of frames in different VLANs even if their
source/destination MAC address is the same.
3
oPer-port configurable learning mode for No Blocking or Secured
(blocking, with static and pseudo-static
4
MACs not blocked).
2
In QinQ frames, the outer tag (tag#1) is the one closest to the Ethernet header. The inner tag is
the one closest to the payload portion of the frame.
3
Some limitations apply. See MAC Address Management section.

oStatic and pseudo-static MAC addresses stored in flash for
guaranteed resumption of operation upon reboot.
oAbility to display the “LAN” MAC address table entries that are
associated with any selected D-PVLAN (and QVLAN, if applicable).
Each local MAC address is displayed along with its type designation
(dynamic, static or pseudo-static) and the local port from which it
has been learned.
1 Gbit/s throughput between ETHER-1000 unit and paddleboard.
Enhanced port security features including blocking of unknown MAC
addresses, intrusion detection and automatic port disabling on cable
disconnect.
Configurable Unit Security mode. High security mode (default) ensures
that none of the unit parameters except those related to SONET-path
provisioning can be modified by non-administrators. Only VistaNET
administrators can change the unit security from High to Low.
Guaranteed delivery of mission critical traffic
oMission-critical traffic can be detected on ingress using the frame‟s
EtherType value. The top priority queues in both “LAN” and “WAN”
switches are reserved for selected EtherType traffic. All other traffic
will use lower priority queues.
o16 separate mapping priority queues per TDM pipe for frames
outputted through the unit's left and right Line (“trunk”) ports (8
queues are for pass-through frames and 8 are for “add” frames).
o8 priority queues for “drop” frames (the frames being passed from
the unit to the paddleboard).
oMonitoring of each of the above priority queues‟ traffic (for
assurance that critical traffic is using the expected queues, and for
debugging traffic paths).
oIn the “LAN” switch, the frames ingressing the paddleboard access
ports (and not matching the selected EtherType) are prioritized
based on each frame‟s source priority (taken from the frame‟s
802.1p/Q priority field, from its „TOS‟ field in the layer-3 “IP” frame,
or from the per-port user-configurable Default Priority).
oThe “WAN” switch prioritizes non-EtherType frames using mapping
priority, which can be set (per access port) to be:
Equal to the frame‟s source priority (except for the frames with
source priority 7, which are mapped with priority 6
5
), or
4
Pseudo-static MAC entries are the entries learned before the port got secured. Pseudo-static
entries do not age out.
5
To ensure that the top priority queue does not get “contaminated” with non-EtherType traffic.

Forced to priority n (n=0, 1…6).
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.
oCopper ports support:
10/100Base-TX Ethernet connections
Half and full duplex operation
Full auto-negotiation for speed and duplex mode with local
LAN devices.
o1-Gbps SFP cages can accommodate either 1000Base-LX or
1000Base-SX optical transceivers with DMI interface.
o100-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.
oAvailable rate limits range from 128 kb/s to 800 Mb/s
oUp 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.
8
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.
8
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

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. These
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).

Supported Topologies
Regardless of the JungleMUX network topology used (point-to-point
10
, linear or
ring), at a node where Ethernet access is required (and the choice is to use
ETHER-1000 unit rather than ETHER-10 or ETHER-100), one ETHER-1000 unit
and one paddleboard assembly are required. At a ring node or add/drop
(intermediate) node in a linear network, Ethernet traffic may be dropped from
either of both directions.
An ETHER-1000 unit is connected with one or more other ETHER-1000 units in
the same JungleMUX network to form a point-to-point, linear or ring ETHER-
1000 network topology. Ethernet ports of all ETHER-1000 units that make up
such a topology create an Ethernet switch with geographically spread access
ports (a “distributed Ethernet switch”). An example of ETHER-1000 ring network
topology is shown in Figure 4. The devices on the LAN segments connected to
ETHER-1000 unit paddleboards at all six sites can exchange traffic through
common bandwidth (N x STS-1 SPE).
10
A point-to-point topology may be considered a special case of a linear network. Two-node ring
topologies are sometimes confused with point-to-point networks. The main difference is the
number of fibers used between the two nodes (two vs. four).

Note: At JungleMUX nodes where Ethernet add/drop is not required, ETHER-
1000 units are not equipped while the STS-1 SPEs used for Ethernet traffic are
passed through.
Bandwidth Partitioning
The SONET bandwidth accessed by ETHER-1000 unit can range from 50 Mb/s
(1 x STS-1 SPE) to 1.2 Gb/s (24 x STS-1 SPE). The unit can partition this
bandwidth into as many as four TDM pipes. Each provisioned TDM pipe can use
from 50 Mb/s to 1.2 Gb/s of bandwidth, to a maximum total of 1.2 Gb/s for all
provisioned TDM pipes (Figure 5). The ETHER-1000 unit has independent traffic
forwarding queues for each TDM pipe, which ensures that traffic carried in
different TDM pipes will be independently queued within the “WAN” switch. This
feature allows for establishing “guaranteed SONET bandwidth” for selected
critical VLANs when multiple VLANs are handled by the same ETHER-1000
system.

Bandwidth Partitioning Examples
At any given JungleMUX node, a TDM pipe is considered “accessed” if:
-all of its STS-1s are assigned to the matching TDM pipe in a local
ETHER-1000 unit;
-the TDM pipe is provisioned in the local ETHER-1000 unit (set for the
proper topology mode);
-at least one of the local ETHER-1000 paddleboard ports has been
provisioned to use a VLAN associated with this TDM pipe.
In the example in Figure 6, each of the four TDM pipes is accessed at all sites.
Since all four pipes have been configured as rings, protection switching is
independently carried out for each TDM pipe. Also, the total amount of STS-1s
used for all 4 pipes cannot exceed 24, which is the limitation imposed by the
ETHER-1000 unit‟s Line port capacity.

Figure 6: Four TDM pipes accessed at every ETHER-1000 unit
The example in Figure 7 shows an application where each TDM pipe is accessed
by a different set of ETHER-1000 units. In particular, the TDM pipe #1 is
accessed at all sites, the TDM pipe #2 is accessed at sites A and E, the TDM
pipe #3 is accessed at sites C and G, while the TDM pipe #4 is accessed at sites
B, C, D, F, G and H. Note that the total amount of STS-1s for all 4 TDM pipes
can now exceed 24.
In Figure 8, there are two ETHER-1000 units at each of the sites A and E (e.g.
main and backup control centers), where potentially more than 1 Gb/s of
Ethernet traffic may need to be added/dropped. The TDM pipe #1 is accessed at
all sites, the TDM pipe #2 at sites A and E, the TDM pipe #3 at sites A, B, C, D
and E, and the TDM pipe #4 at sites A, E, F, G and H. Note that at sites A and E
the two ETHER-1000 units need to be connected to different CBW ports to allow
access to the required bandwidth (total of 44 STS-1s).
