1-Port Channelized OC3 STM-1 ATM CEoP SPA Overview
Table 3-49 describes the 1-Port Channelized OC-3 ATM CEoP SPA LEDs.
1-Port Channelized OC-3 ATM CEoP SPA Interface Specifications
The physical layer interface for the 1-Port Channelized OC-3 ATM CEoP SPA is Optical Carrier-3
(OC-3). The total bandwidth for the SPA is 155.52 Mbps. The 1-Port Channelized OC-3 ATM CEoP SPA
can be channelized to either a maximum of 84 T1s or a maximum of 63 E1s.
Note The 1-Port Channelized OC-3 ATM CEoP SPA can be channelized to E1s, only when SDH framing
mode is used. Channelization to T1s is possible both in SONET and SDH framing mode.
The single SPA port accepts an SFP module with a duplex LC-type receptacle that allows connection to
optical fiber.
1-Port Channelized OC-3 ATM CEoP SPA Optical Transceiver Modules and
Cables
