Chapter: Configuring SONET

Configuring SONET

This module describes how to configure Synchronous Optical NETwork (SONET). SONET defines optical signals and a synchronous frame structure for multiplexed digital traffic. SONET equipment is generally used in North America.

The transport network using SONET provides much more powerful networking capabilities than existing asynchronous systems.

Overview of SONET

SONET is a set of standards that define the rates and formats for optical networks specified in GR–253–CORE. SONET is based on a structure that has a basic frame format and speed. The frame format used by SONET is the Synchronous Transport Signal (STS), with STS-1 as the base-level signal at 51.84 Mbps. An STS-1 frame can be carried in an OC-1 signal.

SONET has a hierarchy of signaling speeds.

Restrictions for SONET

  • Rate combinations on 1-Port OC192/STM-64 or 8-Port OC3/12/48/STM-1/-4/-16 Module are 0-1, 2-3, 4-5, 6-7 and 8. A maximum rate of 4XOC-48 is supported on ports 0-7.

    4XOC-48 can be configured in any one port of a port-group and other port is not used.

  • Only 16 BERT Patterns can be configured at a time on 1-Port OC192/STM-64 or 8-Port OC3/12/48/STM-1/-4/-16 Module.

  • VT1.5 VT cannot be configured if VT1.5 T1/DS1 is configured with the same KLM value.

  • PMON fields are not supported for VT1.5 VT and DS3 or T3.

  • PMON Far-end parameters are not supported.

Restrictions on Bandwidth

  • Total available bandwidth for 1-Port OC192/STM-64 or 8-Port OC3/12/48/STM-1/-4/-16 Module is 10G.

    The following configuration is blocked and an error message is displayed after the maximum bandwidth is utilized: 
    rate OC3| OC12| OC48| OC192
    The bandwidth of adjacent ports should not exceed OC-48.

    The following table shows the bandwidth used by different rates:

    Table 1 Bandwidth Used by Different Rates

    Rate

    OC-3

    155.52 Mbps

    OC-12

    622.08 Mbps

    OC-48

    2.4 Gbps

    OC-192

    9.6 Gbps

Restrictions for Clock Source Configuration

  • Only 4 ports can be configured in SONET line for clock source configuration per chassis.

  • You should configure the clock source line and network-clock sync together to receive the clock from a remote port that is connected to the SONET port.

SONET Switching

SONET Switching is achieved on optical interface modules by circuit emulation. Circuit Emulation (CEM) is a way to carry TDM circuits over packet switched network. CEM embeds TDM bits into packets, encapsulates them into an appropriate header and then sends that through Packet Switched Network (PSN). The receiver side of CEM restores the TDM bit stream from packets.

Modes of CEM:

  • Structure Agnostic TDM over Packet (SAToP) (RFC 4553) – Structure-Agnostic TDM over Packet (SAToP) mode is used to encapsulate T1/E1 or T3/E3 unstructured (unchannelized) services over packet switched networks. In SAToP mode, the bytes are sent out as they arrive on the TDM line. Bytes do not have to be aligned with any framing.

    In this mode, the interface is considered as a continuous framed bit stream. The packetization of the stream is done according to IETF RFC 4553. All signaling is carried transparently as a part of a bit stream.

  • Circuit Emulation Service over Packet (CEP) (RFC 4842) - CEP mode is used to encapsulate SONET payload envelopes (SPEs) like VT1.5 or VT2 or STS-1 or STS-Nc over packet switched networks. In this mode, the bytes from the corresponding SPE are sent out as they arrive on the TDM line. The interface is considered as a continuous framed bit stream. The packetization of the stream is done according to IETF RFC 4842.

SONET Hierarchy

Figure 1. A SONET Link



Each level of the SONET hierarchy terminates its corresponding fields in the SONET payload, as follows:

Section

A section is a single fiber run that can be terminated by a network element (Line or Path) or an optical regenerator.

The main function of the section layer is to properly format the SONET frames, and to convert the electrical signals to optical signals. Section Terminating Equipment (STE) can originate, access, modify, or terminate the section header overhead.

Line

Line-Terminating Equipment (LTE) originates or terminates one or more sections of a line signal. The LTE does the synchronization and multiplexing of information on SONET frames. Multiple lower-level SONET signals can be mixed together to form higher-level SONET signals. An Add/Drop Multiplexer (ADM) is an example of LTE.

Path

Path-Terminating Equipment (PTE) interfaces non-SONET equipment to the SONET network. At this layer, the payload is mapped and demapped into the SONET frame. For example, an STS PTE can assemble 25 1.544 Mbps DS1 signals and insert path overhead to form an STS-1 signal.

This layer is concerned with end-to-end transport of data.

STS-1 and STS-3 Frames

A standard STS-1 frame is nine rows by 90 bytes. The first three bytes of each row represent the Section and Line overhead. These overhead bits comprise framing bits and pointers to different parts of the SONET frame.

Figure 2. STS-1 Frame Structure

There is one column of bytes in the payload that represents the STS path overhead. This column frequently "floats" throughout the frame. Its location in the frame is determined by a pointer in the Section and Line overhead.

The combination of the Section and Line overhead comprises the transport overhead, and the remainder is the SPE.

Figure 3. STS-1 SONET Overhead

For STS-1, a single SONET frame is transmitted in 125 microseconds, or 8000 frames per second. 8000 fps * 810 B/frame = 51.84 Mbs, of which the payload is roughly 49.5 Mbs, enough to encapsulate 28 DS-1s, a full DS-3, or 21 CEPT-1s.

An STS-3 frame is nine rows by 270 bytes. The first nine columns contain the transport overhead section, and the rest is SPE. For both STS-3 and STS-3c, the transport overhead (Line and Section) is the same.

For an STS-3 frame, the SPE contains three separate payloads and three separate path overhead fields. In essence, it is the SPE of three separate STS-1s packed together, one after another.

For more information on Section Overhead, Line Overhead, and Path Overhead, refer the following:

SONET Line and Section Configuration Parameters

The following parameters affect SONET configuration at the line and section levels:

  • Overhead — Sets the SONET overhead bytes in the frame header to a specific standards requirement, or to ensure interoperability with equipment from another vendors.
    • J0 — Sets the J0 or C1 byte value in the SONET section overhead.

      Note

      1 byte, 16 bytes, and 64 bytes are the supported values for J0.

    • S1S0 — Sets the SS bits value of the H1 byte in the SONET line overhead.

  • Loopback — Sets a loopback to test the SONET port.

  • AIS-Shut — Configures the SONET port to send the Alarm Indication Signal (AIS) at shutdown.

  • Shut — Disables an interface.

  • Alarm Reporting — Enables reporting for all or selected alarms.

    • lias —Enables line alarm indication signal.

    • lrdi — Enables line remote defect indication signal.

    • pais — Enables path alarm indication signal.

    • plop — Enables loss of pointer failure signal for a path.

    • pplm — Enables path payload mismatch indication.

    • prdi — Enables path remote defect indication signal.

    • sd-ber — Sets Signal Degrade BER threshold.

  • Clock — Specifies the clock source, where:

    • line —The link uses the recovered clock from the line.

    • internal — The link uses the internal clock source. This is the default setting.

BERT

Bit-Error Rate Testing (BERT) is used for analyzing quality and for problem resolution of digital transmission equipment. BERT tests the quality of an interface by directly comparing a pseudorandom or repetitive test pattern with an identical locally generated test pattern.

The BERT operation is data-intensive. Regular data cannot flow on the path while the test is in progress. The path is reported to be in alarm state when BERT is in progress and restored to a normal state after BERT has been terminated.

The supported BERT patterns are 2^15, 2^20, 2^23, all 0s and all 1s.

BERT is supported in the following two directions:

  • Line - Supports BERT in TDM direction.

  • System - Supports BERT in PSN direction.

The following table shows the SONET level of BERT patterns supported.

  • 2^31 2^31-1 test pattern

  • 2^9 2^9-1 test pattern

Concatenated SONET Frames

Twenty-eight VTs make up one STS-1. Three STS-1s made up an STS-3 and so on. Any one byte within the STS frame has a direct relationship to a base VT that helps to make up the STS.

A lower-case "c" in the STS rate stands for "concatenated", and indicates that the interface hardware is not channelized. Examples of concatenated interfaces are STS-3c and STS-12c.

The STS-1s may be concatenated into sets of 3 or 12 or 24 or 48 or 192 to form STS-3c, STS-12c, and so on. The STS-1s may be combined only at specific STS-n boundaries within an OC port.

SONET Path Level Configuration Parameters

The following parameters affect SONET configuration at the path level:

  • BERT — Starts the BERT test.

  • Clock — Specifies the clock source for a path.

  • Exit — Exits from SONET path configuration mode.

  • Loopback — Sets the entire path in the loopback mode.

  • Mode — Specifies the path operation mode.

  • No — Negates a command or sets its defaults.

  • Overhead — Configures SONET path overhead flags.

  • Shutdown — Disables the SONET path.

  • Threshold — Sets the path BER threshold values.

  • vtg — Sets the VT-15 configuration.

Channelized SONET Frames

A channelized SONET interface is a composite of lower-speed STS streams. However, a channelized SONET interface maintains the streams as independent frames with unique payload pointers. The frames are simply multiplexed before transmission to increase the carrying capacity of the physical fiber. This process is similar to multiplexing 24 digital signal level 0 channels into a DS1 or multiplexing 28 DS1 streams into a DS3.

SONET T1 Configuration Parameters

The following parameters affect SONET T1 configuration:

  • BERT — Starts the BERT test.

  • Clock — Specifies the clock source for T1 interface.

  • Description — Specifies the description of the controller.

  • Framing — Specifies the type of a framing on T1 interface.

  • Loopback — Sets the T1 interface in the loopback mode.

  • Shutdown — Disables the T1 interface.

SONET T3 Configuration Parameters

The following parameters affect SONET T3 configuration:

  • Clock — Specifies the clock source for T3 link.

  • Description — Specifies the description of the controller.

  • Framing — Specifies the type of a framing on T3 interface.

  • Loopback — Sets the T3 link in the loopback mode.

  • Shutdown — Disables the T3 interface.

SONET VT Configuration Parameters

The following parameters affect SONET VT configuration:

  • BERT — Starts the BERT test.

    CEM Group — Specifies the time slots for CEM group mapping.

  • Clock — Specifies the clock source for VT.

  • Description — Specifies the description of the controller.

  • Loopback — Sets the VT in the loopback mode.

  • Overhead — Configures VT line path overhead flags.

  • Shutdown — Disables the VT interface.

  • Threshold — Configures the VT threshold values.

SONET Protection Switching

Automatic protection switching (APS) is a protection mechanism for SONET networks that enables SONET connections to switch to another SONET circuit when a circuit failure occurs. A protection interface serves as the backup interface for the working interface. When the working interface fails, the protection interface quickly assumes its traffic load.

The SONET protection schemes comply with GR-253 and ITU-T G.783. It allows Optical Interface Module to work seamlessly as SONET Add or Drop Multiplexers (ADMs). The implementation of the above protection schemes allows a pair of SONET lines or paths to be configured for line or path redundancy. In the event of a fiber cut, the active line or path switches automatically to the standby line or path up to 60 milliseconds (2/5/10 millisecond for holdover and 50 millisecond switchovers).

Optical Interface Module supports the following SONET protection switching schemes:

  • Linear Bidirectional 1+1 APS

  • Linear Unidirectional 1+1 APS

  • UPSR Path Protection at STS Level

  • UPSR Path Protection at VT Level

1+1 APS

In the 1+1 architecture, there is one working interface (circuit) and one protection interface, and the same payload from the transmitting end is sent to both the receiving ends. The receiving end decides which interface to use. The line overhead (LOH) bytes (K1 and K2) in the SONET frame indicate both status and action.

The protection interfaces need to be configured with an IP address of the chassis that has the working interface, using APS commands. The APS Protect Group Protocol, which runs on top of UDP, provides communication between the process controlling the working interface and the process controlling the protection interface. Using this protocol, interfaces can be switched because of a chassis failure, degradation or loss of channel signal, or manual intervention. In bidirectional mode, the receive and transmit channels are switched as a pair.

Two SONET connections are required to support APS.

The following option is available for linear bidirectional 1+1 APS:
  • Revertive option — For any failure on working line, the software switches to protection line and when the working line recovers, it waits based on the revertive timer and reverts back to working line as active link.

  • Non-revertive option — When the signal fails, the software switches to the protection line and does not automatically revert back to the working line. This is the default option.

The following features are supported on 1+1 APS:

  • SONET PW (SAToP or CEP)

  • SONET local connect

Benefits of APS

The following lists the benefits of APS:

  • APS performs switchovers with minimal loss of data and time-consuming reroutes are avoided.

  • There is no visibility that a failure has occurred beyond the network element in which it is residing; other nodes are not affected by the failure.

  • Implementation of APS guards a network against complex restarts and resynchronizations since failures are isolated to a local device.

  • With APS, the effect of a failure is greatly minimized and a fast switchover guarantees minimal effect on the network.

APS 1+1 for SONET Layer 1 traffic

SONET linear APS 1+1 provides protection against both fiber cuts and front card or back card failures. APS 1+1 requires a redundant protection line for every working line. The traffic is simultaneously carried by the working and the protection lines. Hence, the receiver that terminates the APS 1+1 should select the traffic from one of the lines and continue to forward the traffic. APS 1+1 provides protection in unidirectional and bi-directional modes:

  • Uni-directional Protection: The receiving end can switch from working to protection line without any coordination at the transmit end since both lines transmit the same information.

  • Bi-directional Protection: The receiving end switches from working to protection line by coordinating at the transmit end.

Scenario for Bidirectional APS 1+1

In the above figure, two are connected to provide APS 1+1 bi-directional protection. The highlighted one is the working line and the other is the protection line. The traffic is transmitted on both working and protection lines and received only on one line.

In a scenario where you encounter a fiber cut,

  1. There is a cable cut in the working line. So, the receives a Loss of Signal (LOS) on working line.

  2. starts generating K2 byte and sends it to the over the protection line.

  3. receives the K2 byte and reacts on the receiving K2 byte.

  4. starts sending K1 byte to the on the protection line.

  5. starts sending K2 byte to on the protection line.

  6. receives the K1/K2 byte and starts receiving the data from protection line. The protection line now acts as the active line.

  7. sends K2 byte over the new active line to . receives this signal and starts accepting the data from this new active line.

Scenario for Unidirectional APS 1+1

In the above figure, two are connected to provide APS 1+1 unidirectional protection. The figure shows a working line and a protection line. The traffic is transmitted on both working and protection line and received only on one line.

In a scenario where you encounter a fiber cut,

  1. receives a LOS on RX working line.

  2. detects LOS and starts receiving the data from the protection line. The protection line now becomes the active line.

  3. receives the K2 byte and knows about switching event on device 2.

UPSR Path Protection

A Unidirectional Path Switching Ring (UPSR) is a unidirectional network with two rings, one ring used as the working ring and the other as the protection ring. The same signal flows through both rings, one clockwise and the other counterclockwise. It is called UPSR because monitoring is done at the path layer. A node receives two copies of the electrical signals at the path layer, compares them, and chooses the one with the better quality. If part of a ring between two ADMs fails, the other ring still can guarantee the continuation of data flow. UPSR, like the one-plus-one scheme, has fast failure recovery.

Once a signal fail condition or a signal degrade condition is detected, the hardware initiates an interrupt to software that switches from the working path to the protection path. Non-revertive options are valid for UPSR path protection.


Note
1X OC-192 and 8X OC-48 interface modules only supports the non-revertive option. The non-revertive option is the default mode.

Note

When active link of UPSR and APS is configured on the same interface module and the interface module reloads, the convergence number for UPSR circuits to switch to backup is high ranging from 100 ms to 200 ms. When each circuit is configured separately, the convergence time is always under 50 ms.

The below table gives the maximum number of path level circuits supported in each mode.

Alarms at SONET Layers

SONET equipment detects events and alarms at each of SONET's three layers — section, line and path. Typically, a SONET chassis sends alarms both upstream and downstream in order to notify other devices of the problem condition.

SONET Alarm Surveillance

SONET alarm surveillance uses two terms:

  • State—Condition that is reported or detected. A SONET chassis enters a state when the chassis detects the occurrence of an event. A SONET chassis exits that state when the chassis no longer detects the event.

  • Indication—Prompted by a change of state. This indicates the presence of a condition. This document discusses the Alarm Indication Signal (AIS), and Remote Defect Indicator (RDI).

The interface of active alarm or defect is maintained in a down/down state. The process used to troubleshoot down/down SONET interfaces is similar to that for digital interfaces, such as T1 and T3.

ONS Pluggables

A comprehensive range of pluggable optical modules is available. .

Configuring ONS Pluggables

To configure ONS Pluggables, use the following commands: 

enable
configure terminal
controller mediatype 0/12/0
mode sonet
exit
controller sonet 0/12/0
rate oc3

Verifying the Supported Pluggables

Before you configure the ONS pluggables, use the following commands to verify the supported plugables:

show hw-module subslot <slot/bay> transceiver <port> status: 

The Transceiver in slot 0 subslot 7 port 4 is enabled.
  Module temperature                        = +46.636 C
  Transceiver Tx supply voltage             = 3291.5 mVolts
  Transceiver Tx bias current               = 17264 uAmps
  Transceiver Tx power                      = -2.9 dBm
  Transceiver Rx optical power              = -7.4 dBm

Note
The show hw-module subslot <slot/bay> transceiver <port> status displays as Enabled if the pluggables are supported and the command displays as Disabled if the pluggables are not supported.
