1. BitStorm 1900 IP DSLAM
Introduction
The BitStorm 1900 utilizes patented EtherLoopTM Intelligent Ethernet
technology to provide a robust platform that supports lifeline Plain Old
Telephone Service (POTS) in addition to a variety of new revenuegenerating services ranging from simple high-speed Internet access to
advanced quality video conferencing, multi-stream Video On Demand
(VOD), IP multicast video, and toll-quality Voice over IP (VolP).
The BitStorm 1900 functions as an Internet Protocol Digital Subscriber
Line Access Multiplexer (IP DSLAM) that directs IP data traffic flow
between StormPort™ CPE modems and a data network. The BitStorm
1900 is the backbone component of an EtherLoop, Intelligent
Ethernet™-on-the-Loop, system. Supporting StormPort CPE modems
in voice/data or data-only applications, the multiplexer is located in the
communications room or telco.
Product Overview
The BitStorm 1900 System Components
The basic BitStorm 1900 System includes the BS1900 Shelf (with
circuit packs), Air Baffle, Filter Shelf (s), and a Fan Tray. Depending
on the application, multiple components may be installed and/or
omitted in each rack.
Figure 1-1,“BitStorm 1900 Shelf with Cards and Components,” on
page 2 shows the BitStorm 1900 shelf with the modem cards and basic
components installed.

1-2BitStorm 1900 Installation and Maintenance Guide1900-A2-GN20-00
1. BitStorm 1900 IP DSLAM
The BitStorm 1900 shelf and components are installed in a standard
19” rack and can be installed in 23” racks using optional 23” mounting
ears. Up to five (5) BS1900 Systems can be installed into one rack
depending on the application and the associated required components.
Refer to "Appendix B. Cabling Specifications‚" on page 115 for typical
rack configurations.
Depending on the application/configuration, the following components
are installed in the rack with the BitStorm 1900 Shelf to comprise the
system:
Air Baffle
The Air Baffle, installed above the Filter Shelf (or the BitStorm 1900
Shelf), is used to deflect the exhaust air flow out the rear of the rack.
When more than one BS1900 system is installed in a rack, the Air
Baffle prevents the heated exhaust air of one BS1900 system from
being drawn into the shelf of the BS1900 system installed above.
Fan Tray
The Fan Tray provides forced-air cooling throughout the BS1900
system. A Fan Tray is installed under each BS1900 Shelf and contains
six forced-air cooling fans to ensure sufficient cooling for the entire
system. The -48 V DC Fan Tray is ideal for the CO (Central Office) and
the 110/220 V AC Fan Tray has been uniquely designed for enterprise
applications.
Filter Shelf Option
The Filter Shelf contains low-pass filter splitters to separate out-of
voiceband signals from the voiceband traffic between the BitStorm
modems and the external voice facility equipment. Each Filter Shelf
contains up to 10 filter cards. One filter card supports 12 EtherLoop
lines installed in the BS1900 shelf. Depending on the application, more
than one Filter Shelf can be installed, one on top of another.

Each Filter Shelf can filter up to 120 lines and requires 3RU of rack space.
Filter 66-Block Option
The Filter 66-Block provides the
same POTS splitter function as the
Filter Shelf; however, it is a space
saving and economical alternative
to the Filter Shelf. Using the
lastest technology from Excelsus
Technologies, the Filter 66-Block
integrates a 66-Block with a PCB
(Printed Circuit Board) Filter,
eliminating the need for a Filter
Shelf, saving rack space and
reducing the number of cables
necessary for the installation. Each
Filter 66-Block can filter up to
24 lines.

CO Modem Cards
One BitStorm 1900 shelf supports up to 10 modem cards. Each CO
modem card controls the StormPort CPE modems, directing data traffic
flow between the CPE modems and the data network.
WARNING: POSSIBLE EQUIPMENT DAMAGE! To
comply with Telcordia GR-1089-CORE,
Outside Plant Voltage/Current Limiting
Protection is required for each Outside Plant

Privacy Management
The Privacy Management (a.k.a. MAC Address Filtering) feature
ensures the privacy of each user connected to a local layer 2 network.
StormTracker EMS or the Site Manager is used to enter the MAC
address of a gateway or router to connect to the internet or a local
server in the StormPort CPE modem Privacy Management filter table.
The Privacy Management ensures that downstream packets are
discarded unless they are from one of the MAC addresses in the filter
table and upstream packets are discarded unless they are going to one
of the MAC addresses in the filter table. Thus, it is impossible for a
user connected to one CPE modem to see another user on the same
local L2 network connected to another CPE modem, unless the user’s
1-6BitStorm 1900 Installation and Maintenance Guide1900-A2-GN20-00
1. BitStorm 1900 IP DSLAM
computer’s MAC address is entered into the Priva cy Management filter
table.
NOTE: Creating a filter table on a 10224 CO modem affects all
EtherLoop ports on that card and one of it s CPEs is redund ant,
but possible. However, the CO table should be the same or be a
superset of the CPE table.
Same Card Broadcast
The Same Card Broadcast feature is an option on CO modems that
should be used in conjunction with Privacy Management to provide
secure communications (default is Disabled):
Refer to Table 1-2, “Same Card Broadcast Feature Enabled/Disabled Function for CO Modems,” for the feature function and security issues
associated with each setting.

Spectrum Manager ADSL Protect
The Spectrum Manager software makes EtherLoop spectrally
compatible with asymmetrical services such as ADSL and G.Lite,
detecting and protecting against interference within the same binder . In
addition, EtherLoop in its native state is spectrally compatible with
symmetrical digital services such as T1, HDSL, HDSL2, or SDSL.
Spectrum Manager operates under five modes of operation:
ModeDescription
NativeEtherLoop operates without the analysis of other service activ-
ity in the individual loops.
MonitorSpectrum Manager analyzes other services in the loop that
mance with asymmetric services in the individual loop that
may temporarily af fect Et herLoo p’ s ups tream c apa bility. In this
mode, EtherLoop is forced to “mimic” asymmetric DSL.
Auto-ProtectEtherLoop operates in an Asymmetric Mode if asymmetric
interferers are present. EtherLoop returns to normal upstream
operations once the interference is gone.
Video Protect EtherLoop operates i n a forced Asym metric Mode w ith gu aran-
teed high downstream bandwidth for the delivery of streaming
video applications.
Spectrum Manager-Video Protect
The Spectrum Manager-Video Protect activates the EtherLoop
asymmetrical operation with all upstream traffic limited to a training
speed of 25 (3 Mbps) on theBitStorm 10306 CO modems.
Downstream traffic continues to run as fast as the loop conditions
allow . When this feature is enabled, all nearby EtherLoop lines running
high-speed video downstreams are protected. All CO modems at a site
are required to have the feature enabled by StormTracker Site Manager
or EMS via the MIU SNMP agent.

Passes VLAN Tagged Frames
The BitStorm 1900 is capable of passing 802.1Q tagged Ethernet
frames of 1522 bytes. To implement a VLAN solution, a 802.1Q
tagging switch must exist upstream. Also, an 802.1Q tagging switch or
device must be present on the customer end of the CPE modem.
WAN Interface Cards
The BitStorm 1900 supports the following WAN interface:
The MIU provides remote monitoring and configuration functionality
via SNMP (Simple Network Management Protocol). Through the
SNMP agent, users can remotely manage and configure modem
settings and monitor the performance statistics of all modems in the
BitStorm 1900 system.
1. BitStorm 1900 IP DSLAM
The MIU SNMP agent supports the SNMPv1/RFC 1157 protocol and
supports RFC 1213 MIB II interface groups and the RFC 1493 Bridge
MIB. The MIU SNMP agent also includes an EtherLoop private MIB.
In order to manage the SNMP agent, the user must load our private
MIB into the user’s SNMP Network Manager using the procedure
accompanying the specific Network Management Software (i.e., HP
Openview, etc.).
A list of all supported MIBs and the private MIB can be found in
document 1900-A2-GK40, BitS torm 1900 IP DSLAM Supported SNMP MIBs. This document and private MIBs can be downloaded from the
Paradyne website at www.paradyne.com.

Mixing CO Modem Cards
StormPort CPE Modems
It is possible to fill a BitStorm 1900 shelf with different modem cards
(i.e., five 10306 CO modem cards, and five 10224 CO modem cards).
For the 10306 CO modem cards, Spectrum Manager includes a Video
Protect mode that protects EtherLoop heavy downstream traffic from
disrupting upstream traffic on adjacent EtherLoop lines.
NOTE: The BitStorm 19 00 CO modem ca rd port s ar e provisioned in the
CO & CPE Add/Search functions of the Database module in the
StormTracker Site Manager application. The modem database
is auto-provisioned, identifying the physical shelf slot location

10306 CO Modem IP Multicast Operation
An optional feature of the 10306 CO modem card is the ability to pass
IP Multicast traffic only to the subscribing port. The 10306 modem
card functions as a multi-layer switch and supports IGMP v1/v2 when
connected to the MIU (Management Interface Unit) card via the 100
Base-T Ethernet backplane connection. The 10306 modem creates Port
T able data when a client joins a multicast group and forwards the IGMP
message upstream through the MIU to an IGMP-enabled Switch. When
the IP Multicast data is streamed back to the 10306, it replicates and
forwards the IP Multicast streams ONLY to the ports with subscribing
clients.
