IDU Protection Configuration

Configuration Procedure

Vol. IV-8-20
Before commencing configuration of a protected IDU pairing:
• Ensure the Protection and Ethernet interconnection cables are installed between
the IDU partners.
Providing the protection cable is installed only one IDU can be transmitting.
• Determine which of the partner IDUs is to be configured as primary.
This procedure applies to standard protected IDU operation. For the IDU 20x,
refer to Additional Procedures for IDU 20x on page 8-23, which applies to
operation at capacities greater than 20xE1 or 16xDS1.
A summary of the protection procedure for a new installation is provided below.
For more complete IDU information refer to Procedure Overview for a New
Installation on page 3-7, in Volume IV.
At the outset each IDU must be separately logged into with CT to configure a
network IP address and protection settings (V.24 or Ethernet DHCP login,
depending on the IDU). Once configured, CT screens for both IDUs can be
displayed using an Ethernet NMS connection to just one of the IDU partners.
Configure in turn:
1. Information (terminal and site names).
2. Plug-ins (link, tributary, auxiliary, alarm I/O).
Link and tributary settings must be identical for the partner IDUs.
Auxiliary data functions are not switch-protected.
3. Networking (IP addressing and routing). Configure each IDU partner with a
unique IP address. The network address octets (that which is set with the
network mask) should be common but the host address must be unique.
OSPF or RIP routing is recommended. Static routing can be used but care
must be exercised in networks of two or more hops. See Terminal Protection
Operation and Rules, pt 15.
4. Protection. Select Enable Unit Protection and configure for primary or
8
secondary , and tributary protection type. Refer to Figure 8-6.
At this point, once configurations have been confirmed by clicking Send, CT
screens for both IDUs can be opened using a CT connection to one of the
9
IDUs . Log into one IDU and select its partner by selecting File > New CT >
Partner IDU.
