Description

Single-port channelized OC-3/STM-1 SPA delivering ATM and circuit emulation on SONET/SDH for TDM aggregation and migration use cases. SFP-based optics let you choose short-, intermediate-, or long-reach OC-3/STM-1 transceivers as required. Provides granular channelization down to DS1/E1/DS0, enabling up to 84 T1 or 63 E1 equivalents per port.

Features

- Flexible SFP-based OC-3/STM-1 optics
- ATM and circuit emulation over SONET/SDH
- Granular channelization down to DS0 for TDM aggregation
- Line-rate 155 Mb/s forwarding on the port
- Hot-swappable SPA for minimized downtime
- Fits SIP-based router architectures for scalable WAN edge

FAQs

Q: Does this module require a specific optic?
A: Yes. Use OC-3/STM-1 SFP optics (MMF or SMF) appropriate for your distance; wavelength and reach depend on the chosen SFP.

Q: Can it break out to DS0-level channels?
A: Yes. It supports channelization to DS1/E1/DS0 with up to 84 T1 or 63 E1 equivalents (up to 2016 DS0s).

Q: Is a license required to enable the port?
A: No SPA-specific license is typically required; platform software features may require the appropriate router license.

Q: Which platforms are compatible?
A: It requires a router with SPA Interface Processor (SIP) slots. Refer to your platform’s SPA/SIP compatibility matrix.

Q: Is the SPA hot-swappable?
A: Yes, when used in a supported chassis and software release.
