Chapter 2 NE- and CTM-Specific Details
2.1.9 ONS 15530
2.1.8.6 CTPs
All CTPs are in channelized mode for the ONS 15454 SONET. Alarm monitoring cannot be turned on
or off for CTPs.
2.1.8.7 SNCs
One node supports a maximum of 144 bidirectional STS SNCs with an XC or Cross-Connect Virtual
Tributary (XCVT) card installed or 576 bidirectional STS SNCs with a 10 Gigabit Cross-Connect
(XC10G) card installed. If an XCVT or XC10G card is present, you can create a maximum of 336
bidirectional VT1.5 SNCs.
The SNC name cannot exceed 48 characters. The NE enforces the SNC name character limit.
2.1.8.8 Equipment Protection
1:N equipment protection is supported for DS1, DS3, DS3I, and DS3E cards. You must install protect
cards (DS1N, DS3N, DS3IN, and DS3NE) in slot 3 or slot 15 on the same side of the shelf as the
protected cards. Protect cards must match the cards they protect. For example, a DS1N protects only DS1
or DS1N cards. You must create the protection group. Installing DS1N or DS3N cards in slot 3 or slot 15
does not automatically protect other DS1 or DS3 cards. 1:N equipment protection is always revertive.
1:1 equipment protection is supported for DS1, DS3, DS3I, DS3E, EC-1, and DS3XM cards. Install the
protect card in an odd-numbered slot and install the working card in an adjacent even-numbered slot. For
example, install the protect card in slot 1 and install the working card in slot 2.
2.1.8.9 Facility Protection
Facility protection is available for OC-n PTPs. Protect ports must match the working ports. For example,
port 1 on an OC-3 card is protected only by port 1 on another OC-3 card.
2.1.8.10 Autodiscovery
The ONS 15454 SONET supports automatic discovery of connected elements. CTM can connect to one
node and retrieve information about all connected nodes. The first time CTM connects to a node, it
retrieves only the IP address of the connected node; CTM does not retrieve the node name. However,
CTM must report this element to the users. Because the IP address is unique, CTM initializes the name
of the newly discovered element with the IP address. An object creation event is generated for this
managed element with the IP address as the name. Later, CTM connects to this element and retrieves all
information, including the actual name, and an AVC event is generated for the managed element name.
The NMS listens to the AVC event for the managed element name and invokes
managedElementManager::ManagedElementManager_I:: getManagedElement.
2.1.9 ONS 15530
See the Release Notes for Cisco Transport Manager Release 9.2 for the ONS 15530 software releases
that CTM R9.2 supports.
