About this document
About this document
Purpose
The 5620 SAM NTP Driver Version 1.0.0 Guide provides information about the NTP GNE driver
version 1.0.0, including:
• driver capabilities
• known issues
• discovery and management instructions
The NTP GNE driver extends 5620 SAM management of NTP GNE devices as described in
1.2 “NTP GNE driver capabilities” (p. 5).
You can find more details about the NTP GNE driver in the following guides:

NTP GNE driver description
1 NTP GNE driver description
1.1 Network timing servers in the Small Cell network
The Small Cell access points use network timing servers that run the Network Time Protocol (NTP)
for RF synchronization. The 5620 SAM Small Cell management solution supports Symmetricom
NTP server variants, such as the Symmetricom Time Provider 5000 server. The NTP GNE driver
allows the 5620 SAM to perform fault management of Symmetricomm NTP servers.
1.2 NTP GNE driver capabilities
The NTP GNE driver extends the 5620 SAM fault management support to Symmetricom NTP
servers so that related alarms can be viewed in the 5620 SAM GUI. The NTP GNE driver version
1.0.0 allows the 5620 SAM to perform fault management of NTP servers.
1.3 5620 SAM management
The 5620 SAM supports the following management operations for the NTP NE:
• Discovery
The 5620 SAM discovers the Symmetricom NTP server as an NTP NE.
• Link management
The 5620 SAM monitors the link to the NTP server, raises an alarm when the link fails and
retries automatically for link recovery. When the link is recovered, the 5620 SAM clears the
alarm.
• Fault management
The 5620 SAM normalizes fault events from the NTP server and shows them in the context of
the NTP NE in the 5620 SAM GUI. Alarms are also published over the 5620 SAM-O interface.
See the NTPAlarmDictionary.xml file for details.
• Reach-through to the NTP server from the 5620 SAM GUI
The 5620 SAM GUI provides a launch point option for users to open an SSH session with the
NTP.

Discovery and management
2.3 Limitations
The 5620 SAM support for the NTP in the Small Cell network does not include the following
functions:
• Alarm synchronization
• Configuration management
• Performance management
• Upgrade management
• Inventory management
• Software management
• NE administration and security management
• Auto-discovery
2.4 Restrictions
The following restrictions apply to the 5620 SAM support of the NTP:
• The NTP and the 5620 SAM must belong to the same time zone.
• The NTP does not have a mechanism to determine the sequence of faults or a way to identify
missing traps. Inform messages are not supported.

3 Discovery and management
3.1 Post-installation configuration
This section describes how to discover and use the NTP server in the 5620 SAM after the NTP
GNE driver was installed. See the 5620 SAM GNE Driver Installation Guide for details about
installing a GNE driver.
The following instructions are specific to the NTP server configuration and discovery. See the 5620
SAM User Guide chapter “Device commissioning and management“ for detailed procedures.
Configuring a generic NE profile for the NTP server
Perform the following steps:
1. Choose Administration→Generic NE Manager from the 5620 SAM main menu. The Generic NE
Manager form opens.
2. Click Create, and choose Create Generic NE Profile. The Generic NE Profile (Create) form
opens.
3. Configure the required parameters. The following table list the parameters that need to have
specific values for the NTP GNE. Leave blank the parameter values that are not specified in the
table.

a. Click on the Interface Types tab.
b. Click Add. The Select Generic NE Interface Type form opens.
c. Choose the E1 interface type and click OK.
5. Click on the General tab.
6. Associate the NTP GNE driver with the NE profile.
a. In the Driver Module panel, click Select. The Select Driver Module — Generic NE Profile
form opens.
b. Choose the NTP driver that was installed on the 5620 SAM server and click OK.
7. Save your changes and close the forms.
Configuring an SNMP v2c mediation policy for the NTP GNE
Perform the following steps:
1. Choose Administration→Mediation from the 5620 SAM main menu.
2. Click on the Mediation Security tab.
3. Click Create. The Mediation Policy (Create) form opens.
4. Configure all the required SNMP parameters.
• For Displayed Name, enter NTP.
• Set the Timeout parameter to 40000 milliseconds for the successful discovery of the NTP
GNE.
The mediation policy needs to be configured according to the NE configuration. The Security
Model, Port and Community String parameter values must match the values of the same
parameters configured on the NTP GNE.
5. Save your changes and close the forms.
