2-Port Channelized OC-12/DS0 SPA Interface Specifications
The framer processes incoming and outgoing SONET frames. The framer operates at OC-12c/STM-4
line rates (622.08 Mbps). Packet data is transported with a user-configured encapsulation (such as
Point-to-Point Protocol [PPP]) and mapped into the STS-12c/STM-4 frame.
The 2-Port Channelized OC-12/DS0 SPA interface is compliant with ANSI and Telco standards. The
interface provides support for Management Information Base (MIB) RFC 3592, RFC 2558, RFC 3896,
and RFC 2496.
2-Port Channelized OC-12/DS0 SPA SFP Optical Transceiver Modules and
Cables
The 2-Port Channelized OC-12/DS0 SPA uses a small form-factor pluggable (SFP) optical transceiver
module installed in each port for SONET single-mode and multimode optical fiber connection (see
Figure
Cisco Systems qualifies the optics that are approved for use with its SPAs. The 2-Port Channelized
OC-12/DS0 SPA supports the following types of optical transceiver modules:
