Operation, administration, and maintenance (OAM) features 2-11 A BLSR offers a network-level protection capability, and differs from a UPSR in that the nodes in a BLSR are aware of the larger configuration. In a BLSR, switching nodes communicate to each other through K-bytes. A UPSR node has no network knowledge and does not rely upon any APS communication with other nodes. Protection Protection in a BLSR is provided by using a time slot select function.
2-12 Operation, administration, and maintenance (OAM) features Lockout of working: prevents a protection switch of the working line to the protection line. Lockout of protection: prevents any of the channels from switching to the protection line. Automatically initiated BLSR switching requests • Signal fail (SF) — SF is a hard failure caused by a Loss of Signal, Loss of Frame, a line BER exceeding a preselected threshold, a line AIS, or some other protectable hard failure.
Operation, administration, and maintenance (OAM) features 2-13 BLSR Line Protection Oscillation Control OPTera Metro Release 12.0 introduced a line protection oscillation control mechanism for BLSR systems. If 3 signal failures (SF) are detected on a line within 12 seconds of each other the line protection oscillation control mechanism is activated and protection will be in a lockout condition for 12 seconds. The OPTera Metro 3500 will raise an “Auto Switch Complete Oscillation” alarm.
2-14 Operation, administration, and maintenance (OAM) features BLSR single span Fiber cut example Step Action 1 The BLSR ring is clean. Tributaries are added/dropped at Nodes 1 and 4. 2 The signal from Node 4 to Node 3 is degraded. 3 4 • Node 3 detects failure. • Node 4 is unaware there is a problem. Node 3 sends K-byte messages to Node 4 on the Short and Long paths.
Operation, administration, and maintenance (OAM) features 2-15 BLSR single span Fiber cut example Step Action 6 Node 4 receives the message on the long path, and enters into a ‘Bridged’ state. Node 4 bridges traffic from the incoming working channels to the opposite direction, outgoing protection channels. Node 4 acknowledges receipt of the message by sending a ‘Bridged’ message back to Node 3 on the Long Path.
2-16 Operation, administration, and maintenance (OAM) features BLSR single span Fiber cut example Step Action 9 Node 3 receives the ‘Bridged’ status indication from Node 4. Node 3 enters into the ‘Bridged and Switched’ state. Traffic received on the protection channels are then routed as if they were received from the failed working link. Node 4 then sends a message to Node 3 indicating that it has entered into the ‘Bridged and Switched’ state.

Operation, administration, and maintenance (OAM) features 2-25 BLSR nodal / multi-span failure scenario (involves squelching) In the instance in which one or more nodes becomes disconnected because of multiple line failures and/or nodal failures, a BLSR network enters into a bidirectional protected state of operation. The protection operation is much the same as for the loss of a span, except that add-drop traffic at the affected node is lost.

However, the minimum timeout per request is also one second. So it will take at most three seconds for RADIUS authentication to complete for each server.
Operation, administration, and maintenance (OAM) features 2-127 The Access-Request is submitted to the RADIUS server through the network. If no response is returned within a length of time, the request is re-sent a number of times. Once the RADIUS server receives the request, it validates the sending network processor. If the network processor is valid, the RADIUS server consults a database of users to find the user whose name matches the request.
2-128 Operation, administration, and maintenance (OAM) features Users are able to provision on the SPx: • a network processor as the primary authentication gateway (on the network element) • optionally, a network processor as the secondary authentication gateway (on the network element) Note: A secondary authentication server is supported only if the shelf processor using this server is a member of the spans of control of both network processors acting as authentication gateways (primary and secondary).
Operation, administration, and maintenance (OAM) features 2-129 not store or retain any clear text passwords in non-volatile storage. Encrypted password storage employs the DES and is stored in non-volatile memory for survival of restarts and network processor / shelf processor replacements. Note 1: Any clear text representation of a password on the data entry device is suppressed by the network element. Passwords in clear text are not available to any user, including appropriate administrators.
2-130 Operation, administration, and maintenance (OAM) features The existence of any blocking conditions on the shelf processor and/or the network processor can block the Save and Restore application from executing any further actions. Users are able to check for the existence of Save and Restore blocking conditions. A Save and Restore activity can be terminated at any point before the action is complete. Users can also recommence the Save and Restore application after the application has been arrested.
Operation, administration, and maintenance (OAM) features 2-131 Level 4 • Administration allows complete access to all commands, except for automatic surveillance of all network elements in the network processor span of control.

The double quotes are not included in the length of the password.
Operation, administration, and maintenance (OAM) features 2-137 Users with UPC 1 through 3 will not be allowed to log in if their passwords have expired. There are two password modes for level 1 through 3 accounts: ‘Assigned’ and ‘Valid’. • A user password is in ‘Assigned’ mode when the system administrator was the last person to change the password (that is, initial account creation or user forgot password). At this point, the system administrator and the user both know the password.
2-138 Operation, administration, and maintenance (OAM) features OPTera Metro allows any user with a UPC level 4 and above to add, delete, or retrieve the Access Control List (ACL) for a node. Each OPTera Metro network element supports an ACL which allows a customer to provision nodes onto an allow or deny list. These lists determine whether or not another node is allowed to access the relevant node. The ACL provisioner has the flexibility to define separate outgoing and incoming access.

Table 2-29 on page 2-145 provides the STS1 endpoints to DS1 facility grouping assignments.
2-146 Operation, administration, and maintenance (OAM) features Engineering rules The following engineering rules apply to the STS-1 managed DSM feature: • • • • • • • OPTera Metro 3500 shelves equipped with STX-192 circuit packs (in slots 13 and 14) only supports STS-1 managed DS1 facilities. OPTera Metro 3500 shelves equipped with VTX-series circuit packs (in slots 13 and 14) support both VT and STS-1 managed DS1 facilities.
Operation, administration, and maintenance (OAM) features 2-147 These configurations require synchronization among the network elements to avoid the effects of the SONET synchronous transport signal pointer repositioning within the frame. When a network element is synchronized, all synchronous tributaries and high-speed signals generated by that network element are synchronized to its timing source. Normally, one network element in a ring (UPSR or BLSR) is externally timed.
2-148 Operation, administration, and maintenance (OAM) features Tributary line timing Tributary line timing is shown in Figure 2-49 on page 2-155, example d). When using tributary line timing, a network element derives timing from a received tributary signal. Possible sources of tributary line timing are OC-3, OC-12, OC-48, DS1, and EC-1 facilities. Note 1: Tributary line timing is derived from DS1 circuit pack (NTN430AA, BA) provisioned in OPTera Metro 3500 shelf equipped with VTX-series circuit packs.

Note 2: Supported on shelved equipped with VTX-series circuit packs in slots 13 and 14. The best timing reference source is a high-level stratum clock. Timing modes The four possible timing modes for OPTera Metro 3500 network elements are: • Free run.
2-150 Operation, administration, and maintenance (OAM) features the module automatically enters acquire mode. The maximum time a module can remain in holdover mode is 24 hours. After 24 hours, the module enters the free run mode. Stratum clocks Stratum clocks are stable timing reference signals that are graded according to their accuracy. American National Standards Institute (ANSI) standards have been developed to define four levels of stratum clocks.
Operation, administration, and maintenance (OAM) features 2-151 timing signal quality from a network element in holdover mode in the event a timing reference is disrupted. See Synchronization-status messages on page 2-156.

OPTera Metro 3500 Multiservice Platform NTRN10AN Rel 12.
Operation, administration, and maintenance (OAM) features 2-153 Building-integrated timing supply (BITS) The building-integrated timing supply (BITS) concept requires that all digital equipment in a physical structure must receive timing from the same master clock. This master clock is the most accurate and stable clock in the structure. The BITS is driven by a Stratum 3 or better reference signal.
2-154 Operation, administration, and maintenance (OAM) features When the network element timing mode is set to Internal, the synchronization block in the STX and VTX-series circuit pack produces network element timing without any external timing sources. In Internal timing mode, the STX and VTX-series circuit packs provide a network element timing quality defined in Table 2-32 on page 2-151. External timing External timing is shown in Figure 2-49 on page 2-155, example (b).
Operation, administration, and maintenance (OAM) features 2-155 Tributary line timing Tributary line timing is shown in Figure 2-49 on page 2-155, example (d). When using tributary line timing, a network element derives timing from a received synchronous tributary signal. This signal is used in network elements to synchronize the outgoing transport signals in all directions, and the synchronous tributaries terminated by the network element.
2-156 Operation, administration, and maintenance (OAM) features For an OPTera Metro 3500 system to be synchronized with high-quality timing signals from an external source such as a BITS. If the system contains network elements not connected to external timing sources, then high-quality timing signals must be distributed from the network elements that are connected to external timing sources. The timing signals are distributed in the SONET signal.
Operation, administration, and maintenance (OAM) features 2-157 Synchronization-status messages are carried in bits 5 through 8 of the S1 byte in the SONET line overhead and in the extended superframe (ESF) datalink of the external DS1 signal from a BITS or a tributary. As the timing is passed from one network element to the next, each network element sends SSMs. If the quality of the timing changes, the SSMs inform the next network element of the change. See Table 2-33.
2-158 Operation, administration, and maintenance (OAM) features User-specified quality levels for timing sources A user can specify or override the quality level of an incoming timing source. The user can specify the quality level if the timing source comes from equipment that does not support SSM, such as a BITS or equipment from another vendor. If a user specifies the quality level of a timing source, the user interface appends “-P” to the quality level, for example, ST2-P.

Operation, administration, and maintenance (OAM) features 2-175 ATAG sequence numbers ATAG is a numeric transaction identifier similar to CTAG. The ATAG value is automatically generated by a TL1 agent and is used exclusively as a sequence number for autonomous messages. It is a number from 1 to 999999. The first ATAG used is 1 when the agent first initializes or is reset. The ATAG automatically wraps to 1 for the next autonomous message when the previous message is assigned 999999.
2-176 Operation, administration, and maintenance (OAM) features Two ways to manage VTs on a UPSR are: • Use dedicated STS at each node and provision STS connections at each pass-through VT-managed OPTera Metro 3000 node on the subtending UPSR. This option is simple to implement and prevents VT traffic loss in case of a fiber cut. Figure 2-63 on page 2-176 shows a configuration that uses dedicated STS at each site and Figure 2-64 on page 2-177 shows the same configuration after a fiber cut.
