Purpose
Enters global configuration mode.
Enters SONET controller configuration submode and specifies the
SONET controller name and interface-path-id with the
rack/slot/module/port notation.
Configures the SONET port transmit clock source, where the
internal keyword sets the internal clock and the line keyword sets
the clock recovered from the line.
Use the line keyword whenever clocking is derived from the
•
network. Use the internal keyword when two routers are
connected back to back or over fiber for which no clocking is
available.
line is the default keyword.
•
Internal clocking is required for SRP interfaces.
Note
(Optional) Configures the controller framing with either the sdh
keyword for Synchronous Digital Hierarchy (SDH) framing or the
sonet keyword for SONET framing.
SONET framing (sonet) is the default.
Configures the STS stream specified by number. The ranges are:
1 to 12 on the 2-Port Channelized OC12c/DS0 SPA
•
1 to 48 on the 1 Port Channelized OC48/DS3 SPA
