POS Technology Overview
Packet-over-SONET is a high-speed method of transporting IP traffic between two points. This
technology combines the Point-to-Point Protocol (PPP), High-level Data Link Control (HDLC), or
Frame Relay with Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH)
interfaces.
SONET is an octet-synchronous multiplex scheme defined by the American National Standards Institute
(ANSI) standard (T1.1051988) for optical digital transmission at hierarchical rates from 51.840 Mbps
to 9.95 Gbps (Synchronous Transport Signal, STS-1 to STS-48) and greater. SDH is an equivalent
international standard for optical digital transmission at hierarchical rates from 155.520 Mbps
(Synchronous Transfer Mode-1 [STM-1]) to 9.95 Gbps (STM-16) and greater.
SONET specifications have been defined for single-mode fiber and multimode fiber. The POS SPAs
allow transmission over single-mode and multimode optical fiber at Optical Carrier 3, 12, 48, and 192
(OC-3, OC-12, OC-48, and OC-192) rates.
SONET/SDH transmission rates are integral multiples of 51.840 Mbps. The following transmission
multiples are currently specified and used on the POS SPAs on the Cisco ASR 1000 Series Routers:
• OC-3c/STM-1—155.520 Mbps
• OC-12c/STM-4—622.080 Mbps
• OC-48c/STM-16—2.488 Gbps
• OC-192/STM-64 XFP—9.95 Gbps
