Innovative Prisma IP Architecture
M-Series Optical Access Platform Delivers Reliability
and Scalability
The Prisma IP M-Series chassis is a highly reliable,
complete with redundant switch fabrics and redundant
system controllers. Up to 12 slots are available for user
interface cards. These include 10/100baseT or FX, E1/T1
or DS3 TDM, and Gigabit Ethernet.

The Prisma IP M-Series supports scalable ring speeds from
1 to 20 Gbps using DWDM. A redundant switch fabric is
also provided with scalable redundant serial links from 1 to 5
Gbps to each line card slot. The switching fabric scales to
support 20 Gbps of redundant, bi-directional traffic over the
passive midplane. The line side service interfaces
supported on the M-Series include:

A key advantage of the M-Series architecture is its reliability, ensured by the redundant links from all user cards to
both switch fabric cards and system controller cards. The initial 10 Gbps redundant switch fabric can be upgraded
to 20 Gbps.

Resilient Packet Ring Leadership
Scientific-Atlanta is a leader in the emerging Resilient Packet Ring (RPR) 802.17 standards development due to its
advanced development and actual field deployment of pre-standard RPR systems.
With its Resilient Packet Transport technology, Scientific-Atlanta has enhanced RPR to support innovations such
as distribution of Stratum quality timing, enhanced traffic shaping, congestion management mechanisms, and
DiffServ mapping into MPLS for true Quality of Service and traffic engineering. RPR can utilize the entire ring
topology in both directions, rather than allocating unused protection channels for half of the ring bandwidth, as in
the case of SONET and SDH. For example, a 1 Gbps ring actually offers 2 Gbps of revenue bandwidth.

Innovative DWDM Integration
The Prisma IP M-Series supports integrated DWDM optical components. The Prisma IP DWDM card implements a
novel design that provides high-density and scalability on a per-wavelength basis. The DWDM functionality can be
added as required.
The design of a single DWDM line card incorporates optical multiplexing and demultiplexing of wavelengths, band
filters, hot swappable DWDM transceiver sleds, with all associated fiber management performed internally, multi-
rate 3R regeneration, and direct connections to SONET, Gigabit Ethernet, and Fibre Channel. Each DWDM card
provides long-reach optics with up to 4 wavelengths of 2.5 Gbps wavelengths. Up to six DWDM line cards can be
added into Prisma IP for a total of 24 unidirectional or 12 bi-directional wavelengths. The total ring can support 32
unidirectional or 16 bi-directional wavelengths at 200 GHz spacing.
