Description

Single-port channelized OC-3/STM-1 SPA providing ATM and circuit emulation on SONET/SDH. The W variant offers the same interface and standards support while aligning with specific platform ordering requirements. SFP-based optics enable flexible selection of OC-3/STM-1 reach.

Features

- Channelized OC-3/STM-1 with DS1/E1/DS0 granularity
- ATM + circuit emulation for TDM transport
- SFP-based optics flexibility (choose reach per link budget)
- Hot-swappable SPA for rapid maintenance
- W variant alignment for platform/ordering flexibility

FAQs

Q: What distinguishes the W variant?
A: The W variant aligns with specific platform or ordering requirements while maintaining the same OC-3/STM-1 channelized, ATM, and circuit emulation capabilities.

Q: Which optics are supported?
A: OC-3/STM-1 SFP optics (MMF/SMF). Select SR/IR/LR based on required distance; wavelength and reach depend on the SFP.

Q: Does it support DS0 channelization?
A: Yes. Supports DS1/E1/DS0 channelization up to 84 T1 or 63 E1 (up to 2016 DS0s).

Q: Is this SPA hot-swappable?
A: Yes, when installed in a supported SIP-based chassis.

Q: Do I need additional licenses?
A: No SPA-specific license is typically required; router feature licenses may apply depending on configuration.
