Q & A
Q. What is the Cisco
® ONS 15310-MA SONET Multiservice Platform?
A. The Cisco ONS 15310-MA is a fully redundant, fully protected 6-rack-unit (6-RU) Multiservice Provisioning Platform (MSPP) optimized for metro access networks. It uses the same management interface - the Cisco Transport Controller - as the Cisco ONS 15454, ONS 15600, and ONS 15310-CL platforms, and is fully interoperable with these platforms. The Cisco ONS 15310-MA provides superior circuit scalability (DS-1, DS-3, EC-1, and Ethernet options at both Layer 1 and 2), and includes Small Form-Factor Pluggable (SFP)-based optics capable of OC-3, OC-12, OC-48, and CWDM/DWDM options, plus a wide variety of protection options for up to 99.999 percent reliability.
