Since there is a clear trend of decreasing cost as data rate increases, we will reduce the price per Mbps by another factor of two in estimating the monthly recurring cost of OC-12
Key functions include: SONET/SDH termination at OC-3 or OC-12
; STS12 pointer-processor for ADM applications; cross-connect for up to 12 STS1/STM0s' worth of virtual tributary/tributary units (VT/TUs) and full DS0/E0 mapping capability.
"The CX28560 device offers an ideal solution for increasing the density of channelized OC-12
and OC-48 port card designs," said Ali Mesri, vice president of marketing for WAN PHY products for Mindspeed Technologies.
This customer-premise device is "enterprise-ready" with OC-3, OC-12
and OC-48 connectivity, enabling the majority of enterprises to easily connect their storage networks to carriers' ubiquitous SONET services for high-performance, cost-effective extended storage networking.
The initial BroadCipher ATM product supports bandwidth from E3 (34Mb/s) to OC-12
The access points are linked together by an OC-12
core backbone, which can be upgraded when added capacity is needed.
The CHESS chip set provides SONET/SDH framing capability at each of the key OC-3, OC-12
and OC-48 optical line rates.
At the time of delivery will be required to run two streams of access: 1GE and OC-12
. The system must also be provided with the CWDM optical multiplexers to connect the external transmission PDH.
The device is also useful wherever a design engineer needs to switch differential pairs of LVDS or LVPECL signals to support signaling line rates of SONET OC-12
They also provide multi-mode to single-mode and dual fiber to single fiber conversion for Ethernet, T-1, E-1, OC-3 and OC-12
In addition to the CellBus(R) family, TranSwitch has a complete range of products that serve the access market and complement ASPEN, including the announced PHAST-3 and PHAST-12 SONET/SDH overhead processors which support cell, packet and PDH transport over OC-3 and OC-12
In addition to low- and high-speed ATM access, the switch facilitates frame relay and circuit emulation services at T1/E1, T3/E3 and OC-12
