Multiple Management Paths. Provides multiple methods for sending/
receiving management data.
— Embedded Data Link (EDL). Provides a path for management data over
a performance channel between two nodes. The performance channel
uses 8 Kbps of bandwidth, and is embedded in the synchronous data
channel. If you choose this method, you must have a Sync Data port.
—
Direct Data Link (DDL). Provides a path between two nodes over the
T1/FT1 link itself, embedding the management data in the T1 bundle.
The management data always uses 1 DS0 (64 Kbps).
— Facility Data Link (FDL). Provides the management path over the FDL of
the DS1 extended superframe (ESF). Using this method does not use
any customer data bandwidth, but requires end-to-end connectivity. If you
select this method, you may need to work with your service provider to
ensure that ESF framing is used and the required FDL management path
exists end-to-end.
— COM Port. Provides a physical path over the communications
port/interface for local user interface access or network IP connectivity
data management.
IP Connectivity. Supports connectivity within an IP network for up to 300 IP
host and/or network routes. Using the four management paths described
above, provides IP routing for SNMP, Telnet, and file transfer protocol (FTP)
messages connectivity without requiring direct connections.
DSX-1 Drop and Insert port(s) allows DTEs/PBXs that support the DS1
signal format to share the T1 network with other high-speed equipment. One
DSX-1 port is provided on the 9161 T1 NAM. The DSX APM (for use with the
9261 T1 NAM) provides two drop/insert ports.
Alarm and Fault Condition Indication. Provides the capability of attaching
a terminal or printer to display/print alarm messages.
Alarms or traps that are generated include: power supply, loss of signal, out
of frame, alarm indication signal, excessive error rate, primary and secondary
clock failure, yellow alarm signal received, misconfiguration, and APM failure.
