Cisco uBR10-SRP-OC12SML DPT WAN Line Card
The Cisco uBR10 Spatial Reuse Protocol (SRP) OC12 single-mode fiber, long-reach (SML) dynamic
packet transport (DPT) WAN line card provides shared IP over SONET capability for the
Cisco uBR10012 router platform.

Cisco uBR10012 OC-48 DPT/POS Interface Module
The Cisco uBR10012 OC-48 dynamic packet transport (DPT) and packet-over-SONET interface module
is a full-height line card for the Cisco uBR10012 universal broadband router. This card provides trunk
uplink capabilities that support up to 1.4 Gbps full duplex throughput over a standard SONET/ITU-T
Synchronous Digital Hierarchy (SDH) interface, using a single mode fiber with SC connectors.
Two versions of the Cisco uBR10012 OC-48 DPT/POS interface module are available— short reach
(SR) or long reach (LR). Both versions work with the performance routing engine (PRE).
The Cisco uBR10012 OC-48 DPT/POS interface module provides a point-to-point connection to a
backbone router and encapsulates IP Packets with byte-wise HDLC framing, placing them directly into
the OC-48 SONET (or SDH) payload.
The Cisco uBR10012 OC-48 DPT/POS interface module is a standard implementation of packet over
SONET switching, and supports the following features:
•
OC-48 bandwidth between the line card and the PRE.
•
North American (SONET) and European (SDH) formats
•
Automatic protection switching (APS)
•
Alarm processing
Note
Two Cisco uBR10012 OC-48 DPT/POS interface modules are required when using the card when using
the card in DPT mode in a Cisco uBR10012 universal broadband router.
