Cisco 2600/2600XM AND 3600 SERIES 8 PORT T1 ATM MODULE WITH IMA 规格指南
IMA is an ATM Forum specification that provides a
cost-effective and scalable alternative to T3/E3 services by
allowing carriers to leverage widely available T1 services
over ATM and interoperate with other vendors’
standards-based equipment. Multiport T1/E1 IMA can
provide organizations with highly desired fractional T3
bandwidth connectivity, which is critical in situations where
DS3 or OC-3 fiber connections are either cost-prohibitive, or
unavailable between a provider’s central office and the
customer’s premises.
