Engineering rules
The following engineering rules apply to the test access feature:
• Optical TAPs must be in unprotected mode.
• A TAP can simultaneously accommodate connections form more than one
interface (until the TAP capacity is reached).
• For shelves equipped with the STX-192 circuit pack, the SONET signal
routed to the TAP is down to STS-1 granularity and can include
concatenated paths or whole line to the 2.48 Gbit/s rate accommodate.
• For shelves equipped with the VTX-series circuit pack, the SONET signal
routed to the TAP is down to VT1.5 granularity and can include
concatenated paths or whole line to the 622 Mbit/s rate accommodate.
• Multiple test access ports can be provisioned on an OPTera Metro 3500
shelf.
— The maximum number of TAPs that can be provisioned on a shelf is
equal to the maximum number of working ports the shelf configuration
can support in slots 3 through 10.
• If a test access session (monitor or split) is active, changing the protection
scheme for any electrical or optical interface on the network element is
prevented.
• The TAP must be defined before a test access connection can be
provisioned
• Only test access connections can use the TAP.
• Optical interfaces in slots 11 and 12 can not be used as test access ports.
• Test access connections are deleted and original connections restored:
— if the SPx or the circuit pack of the TAP is replaced.
— during SPx or the circuit pack of the TAP restarts (warm/cold).
— during brownouts.
• Test access connections are maintained:
— during restarts (warm/cold) of interface under test.
User interface
Site Manager
Site Manager Release 6.0 introduced a new application called Test Access
Session Management. This application allows user to manage their test access
sessions from Site Manager. This application is a nodal application, so test
access sessions can only be managed on one network element.
