Units that have the basic diagnostic feature set can be upgraded to:
zFull Service Level Management (SLM). This adds real-time and historical network
performance monitoring and SLA (Service Level Agreement) reporting capabilities to your
iMarc unit and network.
zSLM with Application Monitoring. In addition to the features of SLM, this adds the ability
to measure user-defined Layer 4 and above traffic.
To upgrade your system, order a Feature Activation Certificate and provide the model to be
activated, your OpenLane®SLM system license key number, and the number of iMarc units to
be activated to SLM or SLM with Application Monitoring capability.
OpenLane SLM Release 5.3 or above is required to schedule activation of SLM features in units,
and to manage the number of activations remaining on the certificate. OpenLane SLM Release
5.7.1 or above is required to activate SLM with Application Monitoring.
When the Feature Activation Certificate arrives, add the Activation Certificate Number to your
OpenLane SLM application’s database. Activations can occur at any time, for as many units as
desired, until no activations remain for the certificate.

Automatic Configuration
The iMarc unit provides several automatic configuration features. Frame Relay Discovery and
configuration is one of these features.
Main Menu → Auto-Configuration
The default discovery mode is 1MPort. In this mode, for each DLCI discovered on the network,
the unit creates a network interface DLCI containing two EDLCIs (Embedded DLCIs – one for
user data and the other for management), a Port-1(or DSX-1, if it is the user data port) DLCI with
the same number, and a management PVC, then cross-connects them.
NOTE:
When auto-configuration creates a multiplexed DLCI, but a standard DLCI is needed,
change the DLCI to Standard from the network DLCI Records screen: Configuration →
Network → DLCI Records
Other modes can be selected. See Setting Up Automatic Configuration in the iMarc SLV
Configuration Reference for information about other modes and how the Frame Relay Discovery
Mode can be changed.
No automatic configuration occurs until the network cable is connected. If you do not want
management links configured or automatic configuration, change the default setting for the
Frame Relay Discovery feature.
Time Slot Assignment
Network time slots are discovered automatically when Time Slot Discovery is enabled (the
default setting) on the Frame Relay Network 1 Assignments screen. This feature can be disabled
if you want to manually configure time slots.
See Assigning Time Slots/Cross Connections in the iMarc SLV Configuration Reference for
additional information about this feature.

4Save the phone number(s).

9126-A2-ZN11-40 19
Setting Up to Use the Modem PassThru Feature
The Modem PassThru feature allows access to the router via a dial-up connection to the unit.
When this feature is set up and active, a logical connection between the unit’s modem and COM
ports is made, and data received over the modem port is transmitted out the COM port to the
router’s auxiliary (AUX) serial port. When an escape sequence (minus, minus, minus) is
detected, the iMarc unit switches back to normal user interface operation. If this feature will be
used, the COM port must be configured for that use.
Procedure
1Configure the COM port to use Modem PassThru.
Main Menu →Configuration → Management and Communication →
Communication Port
