This chapter provides procedures for changing the default transmission parameters and performance monitoring (PM) thresholds for Cisco ONS 15454 SDH electrical and optical cards. The chapter also provides procedures for converting the E1-N-14 and DS3i-N-12 cards from 1:1 to 1:N protection (E3-12 only supports 1:1 protection).
Because much of the electrical and optical card provisioning involves PM thresholds, refer to the Cisco ONS 15454 SDH Troubleshooting and Maintenance Guide for definitions and general information about ONS 15454 SDH performance monitoring parameters. In addition, refer to the ITU-T G.707, G.783, and G.841 documents. The default thresholds delivered with ONS 15454 SDH cards are based on specifications contained in those documents.
Note You start Cisco Transport Controller (CTC) using your web browser and typing the IP address of the
ONS15454 SDH shelf to be controlled into the address bar. You have to use a login with Provisioning
or Superuser authority. Starting the CTC can take a few minutes depending on the speed of your IP
connection to the ONS15454 SDH shelf. After having typed the IP address into the address bar, CTC
will start with screens like the ones as shown in
Figure 7-1,
Figure 7-2, and
Figure 7-3.
Figure 7-1 CTC login prompt
Figure 7-2 Reaction of the web browser after login
Downloading CTC from the ONS15454 SDH node can take up to a few minutes, depending on the speed of the web connection to the node to be controlled.

7.1 Front Mount Electrical Connection (FMEC) Cards
The ONS 15454 SDH Front Mount Electrical Connection (FMEC) cards are only feedthrough cards to enable front access for the interfaces. They do not require any parameters to be set during provisioning. The only internal data that these cards have is inventory data.
The FMEC cards are:
FMEC-E1
FMEC-E3/DS3
FMEC-DS1/E1
MIC-A/P
MIC-C/T/P
7.2 Provisioning Electrical Cards
The ONS 15454 SDH electrical cards are pre-provisioned with settings that you can modify to manage transmission quality.
The electrical cards are:
E1-N-14
E3-12
DS3i-N-12
When you open a card in CTC (which means double-click on this card) and choose the Provisioning tab, the following subtabs are commonly displayed:
Line—Sets line setup parameters, such as line type, line coding, and line length. This is also where you put ports in and out of service.
Line Thrshld—Sets the line-level PM thresholds.
Elect Path Thrshld—Sets the path-level PM thresholds for electrical (E1, E3, DS3) traffic.
SDH Thrshld—Sets the path-level PM thresholds for SDH traffic.
Alarming—Sets alarm profiles for individual ports. See "Alarm Monitoring and Management." for information about creating alarm profiles.
As an example, Figure 7-4 shows the screen with the choices for an E1-N-14 card.

7.3 Converting E1-N14 and DS-3i-N-12 Cards From 1:1 to 1:N Protection
The ONS 15454 SDH provides several protection options for E1-N14 and DS-3i-N-12 cards: unprotected, 1:1, and 1:N (N=5 or less). Changing protection from 1:1 to 1:N increases the available bandwidth because two of the three cards used for protection in the 1:1 protection group become working cards in the 1:N group.
When setting up 1:N protection, install the E1-N14 or DS-3i-N-12 card in Slot 3 or 15 on the same side of the ONS 15454 SDH as the cards it protects. Slot 3 protects cards in Slots 1 - 2 and 4 - 6. Slot 15 protects Slots 12-14 and 16-17. An E1-N14 or DS-3i-N-12 card installed in Slot 3 or 15 can protect up to five E1-N14 or DS-3i-N-12 cards. If you install a DS-3i-N-12 or E1-N14 card in another slot, it is not able to protect other E1-N14 or DS-3i-N-12 cards in 1:N protection.
7.3.1 Convert E1-N14 Cards From 1:1 to 1:N Protection
Purpose
Setting E1-N14 cards to 1:N protection

Intermediate-Path Performance Monitoring (IPPM) allows you to transparently monitor traffic originating on E-1, E-3, and DS-3 cards (Path Terminating Equipment) as it passes through STM-1, STM-4, STM-16, and STM-64 cards (Line Terminating Equipment). To use IPPM, you create the VC4 circuit on the E-1, E-3 or DS-3 cards, then enable IPPM on the STM-N cards that carry the circuit.
Near-end performance monitoring data on individual VC4 payloads is available by enabling IPPM.
For example, suppose you have a VC4 circuit that originates and terminates on E-N cards at Nodes 1 and 4. You want to monitor the circuit as it passes through STM-N cards at Nodes 2 and 3. To do this, open the STM-N card, select the Provisioning > VC4 tabs, and check Enable IPPM for the appropriate VC4, in this example, Line 1, VC4 1 (Figure 7-6).
Figure 7-6 IPPM provisioned for VC4 on an OC-3 STM-1 card
After enabling IPPM, performance is displayed on the Performance tab for the STM-N card. IPPM enables per-path statistics for VC4 CV-P (coding violations), VC4 ES-P (errored seconds), VC4 FC-P (failure count), VC4 SES-P (severely errored seconds), and VC4 UAS-P (unavailable seconds). Only one VC4 per port can be monitored at one time. For additional information about ONS 15454 SDH performance monitoring, see to "SDH Performance Monitoring."
7.5 Provisioning Optical Cards
This section explains how to provision line and threshold settings for OC-N /STM-N cards and how to provision OC-N /STM-N cards for SDH.
Note The general expression OC-N/STM-N is chosen because the numbering in SONET (OC-N) and SDH
(STM-N) are not the same. OC-3 corresponds with STM-1, etc.
The OC-N /STM-N abbreviation stands for any of the following cards:
OC3 IR 4/STM1 SH 1310
OC12 IR/STM4 SH 1310
OC12 LR/STM4 LH 1310
OC12 LR/STM4 LH 1550
OC48 IR/STM16 SH AS 1310
OC48 LR/STM16 LH AS 1550
OC48 ELR/STM16 EH 100 GHz
OC192 LR/STM64 LH 1550
The OC48 ELR/STM16 EH 100 GHz cards are available in eighteen different wavelength versions for Dense Wavelength Division Multiplexing DWDM; refer to the OC48 ELR/STM 16 EH 100 GHz Card Specifications section in the Cisco ONS 15454 SDH Troubleshooting and Maintenance Guide, Release 3.3 for a table of available wavelengths. In the following tables, all these cards are abbreviated as STM-1, STM-4, STM-16, and STM-64.
7.5.1 Modifying Transmission Quality
The STM-1, STM-4, STM-16 and STM-64 cards are pre-provisioned with settings that you can modify to manage transmission quality. For each optical card, you can specify thresholds for near and far end nodes at the Line, Section, and Path levels for 15-minute and one day intervals. Depending on the card, you can specify Line, Section, and Path thresholds.

Step 1 Display the OC-N /STM-N card in CTC card view.
The ONS 15454 SDH currently supports 1+1 span protection to create redundancy for optical cards. Optical cards in any two slots can be paired for protection. 1+1 protection pairs a single working card with a single dedicated protect card. If the working card fails, the protect cards takes over.
With non-revertive 1+1 protection, when a failure occurs and the signal switches from the working card to the protect card, the signal stays switched to the protect card until it is manually switched back. Revertive 1+1 protection automatically switches the signal back to the working card when the working card comes back online.
7.7 Provisioning Ethernet Cards
Three Ethernet cards are available for the ONS15454 SDH.
