CSCO doesn't have a true OC-48 multiservice ATM core switch. I already inquired about this. CSCO's fastest switch is the OC-12 BXM-622 ATM switch. Neither does NN. FORE's ForeRunner ASN-9000 which has a backplan capacity of 1.6 Gbps and can support up to four OC-3c(155 Mbps) connections. FORE's ASX-1000 is a scalable 2.5 Gbps to 10 Gbps backbone switch supporting up to 128 ATM ports. Whereas, The Ascend GX 550 Physical Interface Modules reside in the modular GX 550 platform and provide industry- standard SONET/SDH connections to external equipment. Up to four Physical Interface Modules are paired with a Base I/O Module that provides the higher layer ATM cell processing. Each Base I/O Module can host four 4-port OC3/STM-1 Physical Interface Modules, four single-port OC12/STM-4 Physical Interface Modules or one single-port OC48/STM-16 Physical Interface Module. For additional flexibility, each Base I/O can support a mix of 4-port OC3/STM-1 and single port OC12/STM-4 modules. The GX 550 provides industry-leading port density with 160 OC3/STM-1, 40 OC12/STM-4, and 10 OC48/STM-16 ports per switch, 25 - 100 Gbps backplane capacity. It is indeed true that ASND is at least 6 mos ahead of competition. Cosidering that we are in the Internet dog time, 6 mos is enough for ASND to conquer the market, build a large installed base of WAN backbone edge/core ATM switch. In the NW biz, this is a huge advantage because customers must have a very good reason to switch vendors for too much money has already been invested in traininng, NW installation & mgmt & configuration, testing, qualifying, interoperability. We are talking about the total cost of ownership here instead of the initial cost of equipment purchase.
