if no power is present. The status LED is green when operationally up, amber when operationally
down, off when administratively shutdown and blinking green during initialization. The link state
LED is green when the link is established; amber when the link is down; and unlit when the port is
shutdown.

SONET/ SDH Path Attributes

Any CES path can only be configured to operate in access mode. Each path has a configurable text
description. The SONET/SDH signal label byte (C2) is configurable. The SONET/SDH path trace
string (J1) is configurable. Payload scrambling can not be enabled on CES paths. The valid
SONET and SDH path configurations are shown in

All SONET/SDH path alarms are configurable to be either enabled (the default) or disabled. The
MTU size is configurable per path in the range of 512 to 2092. The path uses a default MTU size
set to equal the largest possible CES packet size.
Load balancing options are not applicable to channelized CES paths.
