Introduction

C HAPTER

HAPTER

ENERAL

FrameStart is an intuitive frame-relay configuration, analysis, and diagnostic feature set that incorporates the capabilities of expensive test analysis equipment into the functionality of a high-quality line of CSU/DSU products.

The Verilink FrameStart engine operates at wire-speed to deliver the most economical frame relay diagnostic information in the industry today for the price. The price-to-performance ratio of this product line is unequaled when compared to any of the major brand providers.

The DDS CSU/DSU Network unit is a synchronous Digital Data Service CSU / DSU with FrameStart capability targeted at frame-relay applications. The DDS CSU/DSU also provides many useful diagnostic features and operates in standard DDS I and DDS II modes. This product operates in a frame-relay environment or on private (leased) line applications in a point-topoint environment.

The T1 Network unit is a T1 CSU/DSU with FrameStart capability and operates at fractional T1 rates up to a full T1 carrier service. This product also operates in a frame-relay environment, leased line service, or LDM (limited distance m odem) p rivate-lin e applica tions.

The FrameStart FSE E1 Network unit is an E1 CSU/DSU with FrameStart capability and opera tes at fr actional E1 rates up to a full E1 carrier ser vice. This product also operates in a frame-relay environment, leased line service, or LDM (limited distance modem) private-line applications.

Verilink has two options available in the FrameStart family of products-FrameStart Install a nd Fra meStart M onitor--fo r both t he DDS a nd T1 CSU DSU units. The FrameStart FSE unit has an option for the FrameStart Monitor only.

General 3

FrameStart Install Mode

FrameStart Install has four major benefits that offer significant value when comparing to other products:

• LMI Sourcing - A frame relay poll ing function that determines the LMI type

and qualifies the traf fic to the frame relay switch. All DLCI information for virtual circuits is c ollected and displayed on the LCD.

• End-to-End Integrity - PVC discovery modes determine critical parameters

from the remote units to verify the integ rity of the network upon initial installation.

• PVC Delay Testing - test capabilities for each virtual circuit regarding delay

characteristics. The delay measurement can be used to detect a problem circuit upon instal lation by providing a snapshot of the network delay.

• WAN Receive Level - isolate WAN problems very quickly upon installation

by monitoring network quality dur ing installation.

FrameStart Install is a network-intrusive mode that does not require any data equipment such as a router of FRAD to operate. If a router is connected, operation is halted to perform the installation diagnostics.

FrameStart Monitor Mode (optional)

FrameStart Monitor adds more capabilities to monitor real-time network conditions in a non-intrusive state when connected in real-world applications:

• LMI Monitoring - durin g normal operation to update DLCI tables and

indicate local and remote alar m conditions on the frame relay network.

• LMI Auto Sourcing - automatically initiates LMI sourcing if the router fails

and indicates an alarm condit ion.

• SOS Mode - f rame broadcasts from failed units i n the field to quickly isolate

failed circuit s within the network and indicates an alarm condition.

• New Circuit Insta ll - detects when new DLCIs are added in the network and

allows for network information to be collected from the remote unit during installation.

• Real-ti me PVC delay testing is not supported in Monitor Mode.

NOTICE: FrameStart Monitor is available from the factory or as a field

upgrade using an EPROM replacement.

The DDS and T1 CSU/DSU units perform all of these functions without expensiv e software packages or a sep arate G UI interfa ce. The integral LCD shows this information.

We believe that the best solutions are still the simple ones, that actually provide the data you need to quickly configure, install, test, and validate the integrity of your data network. The Verilink FrameStart feature set was created with this in mind, and simplifies the installation and troubleshooting of frame-relay circuits and ongoing maintenance of the overall data network.

4 FrameStart DDS CSU/DSU and T1 CSU/DSU and FrameStart FSE

What is LMI Sourcing and why is it important?

In the mo st basic i mplement ation, F rame Rela y is a s imple int erface t hat offers bandwidth on demand with low latency and high throughput. The UNI is the user-to-network interface and the LMI (local management interface) enables both the user and the network to gather information about the UNI. The LMI allows the user and frame relay network to signal each other about several activities pertaining to the permanent virtual circuits (DLCIs) on the link and their physical link status. The LMI provides the following services:

• A polling functi on to test whether the user or network machine is connected

to the interface

• A set of operations tha t inform the user of the addition or deletion of virtual

circuits at the interf ace

• A report on t he sta tus of a ll vir tual cir cuits o n the int erf ace that st ates whether

or not a virtual circuit is active

• A report on the availability of a new virtual circuit.

LMI information is published in ANSI T1.617, Annex D; ITU-T Q.933, Annex A; and LMI Revision 1.0.

LMI

What is a DLCI?

A DLCI is a data link connection identifier, and is a unique number for each permanent virtual circuit (PVC) in the frame relay network. The following DLCI values have been designated for the frame relay network:

0 LMI Channel for ANSI and ITU

1–15 Reserved

16 – 991 For user virtual circuits

992 – 1007 Layer 2 management of bearer service

1008–1022 Reserved

1023 In-channel layer management for LMI Revision 1.0

What messages does LMI provide?

LMI provides for two message types that include a status (S) message and a status enquiry (SE) message. The SE message is invoked based on a timer with an upper and lower limit, and the receiving machine responds with a status message. Depending on the timers and counters used for LMI, the status ele ment can b e either a statu s request t hat acts as a link v erificat ion request, or a full status (FS) request that also includes information on all PVCs on the circuit.

General 5

What is PVC Discovery in FrameStart?

Verilink has included support for PVC discovery at the remote end of each end-to-end permanent virtual circuit. For the DDS and T1 CSU/DSU units, this mode is initiated by the user upon installation and configuration of each logical port in the network. Verilink takes advantage of RFC 1490 rules for encapsulating data within the Frame Relay frame, and incorporates PVC extensions for establishing a virtual loopback on each PVC to determine the remote link characteristics. This information includes remote DLCI numbers, unit identification, link status, and optional fields such as committed information rates (CIR) and circuit delay. The user enables this operation for all active DLCIs on the circuit by setting LMI Mode to On.

What is PVC Delay Testing?

FrameStart allows the user to test an active PVC for delay characteristics. A DLCI can be selected and a delay calculation is performed end-to-end to determin e the perfo rmance ch aracte ristics of a particular circuit . This operation is enabled by the user for any active DLCI on the circuit.

What is a WAN receive le vel?

On any transmission network, the signal level indicates the strength of the phys ical tr ansp ort sys tem. The bet ter the signa l leve l, the be tter the performance of the transmission system. Expensive analyzers are used today to measure the signal level performance of the transmission network before data networks are installed. The DDS and T1 CSU/DSU units provide a simple diagnostic to display the receive level from the network unit. This removes the need to have additional test equipment on site when installing data networking components.

What is LMI Monitoring?

During normal operation conditions, FrameStart Monitor continually monitors LMI traffic on the network to update DLCI tables in the unit. FrameStart automatically detects new circuits or indicates an Alarm condition for inactive circuits.

What is LMI Auto Sourcing?

During normal operating conditions, FrameStart automatically detects a failure with the data equipment (router) and takes control of the circuit to keep the network alive. This allows for quick fault isolation of the problem. When the data equipment returns to service, FrameStart reverts to monitor mode.

What is SOS Mode?

During LMI Auto Sourcing, the unit can be configured to send a SOS frame to the host site and indicate an alarm condition on a particular virtual circuit. This makes remote troubleshooting and fault isolation quick and easy.

6 FrameStart DDS CSU/DSU and T1 CSU/DSU and FrameStart FSE

What is New Circuit Install?

In normal FrameStart Install mode, data-flow from the Router is stopped. This feature allows FrameStart to detect new circuits and perform PVC discovery on new installations without interrupting service to the rest of the network.

How does FrameStart work in a typical application?

FrameStart includes three different operating modes for ease of operation.

INSTALL: LMI Mode is ON

In Install mode, the unit performs LMI sourcing based on the assumption that data equipment is not available. The DDS and T1 CSU/DSU units source LMI to the frame rel ay net work, and record the status in formati on for dis play on the LCD. This includes the type of LMI, the number of DLCIs, and the status of each PVC. User initiated menus exist in the LCD to activate PVC discovery and PVC delay measurements on active DLCIs. After installation is complete, set LMI Mode to OFF for normal operation.

MONITOR: LMI Mode is MON (Optional Feature)

In Monitor mode, the unit is in a non-intrusive state between the network and the data equipment monitoring the activity on the frame relay circuit. If the unit stops receiving LMI status responses from the network, the unit will automatically SOURCE LMI to verify the network connection is still active. After verification, the unit will revert to a non-intrusive monitoring mode. Real-time PVC delay testing is not available in this mode. Also, SOS mode can be enab led or d isabled to g enerate alarms t o a host uni t. New ci rcuits ca n be added to a network and automatically detected based on the LMI information. A specific DLCI can be selected to perform PVC discovery in order to verify the end-to-end integrity of the new circuit without disrupting normal operation of the overall network.

OFF: LMI Mode is OFF

In the OFF mode, FrameStart is not required based on the unit operating in a private-line application or after the installation of frame relay circuits is complete. Receive Levels are still displayed for the TDM network unit.

FrameStart Benefits

FrameStart equipment presents a distinct advantage over routers with integral CSU/DSU transmission devices. FrameStart Install and Monitor provide test capabilities that traditional CSU/DSUs cannot provide. Also, FrameStart is a more economical solution than routers with integral CSU/DSUs that sell for around $1,000 or more, and provide minimal diagnostic capabilities. Verilink DDS and T1 CSU/DSU units bring your application back to the true functions of “Intelligent” CSUs/DSUs to provide a clear point of demarcation between

General 7

the WAN and router. Fault isolation is greatly simplified with FrameStart during installation and normal service. FrameStart Install reduces the cost of installation and allows service providers to quickly install new frame relay circuits. FrameStart Monitor makes fault isolation quick and easy, and reduces the overall support needs and costs of managing a complex data-critical network.

Operation 27

Monitor Mo d e . When the unit is in monitor mode (LM) and LMI Mode is

configured for MON, individual selection of PVC discovery and delay is allowed by pressing SELECT while in the DLCI screen. Test DLCI xxx? is displayed. Pressing SELECT performs the test as follows. The unit sets up a mask for this one circuit and sends PVC discovery and PVC delay approximately every second. This minimizes the traffic disruption on the circuit. The screen then ret urns to the previo us perfo rmance screen wh ere the fields are updated when the information is collected. Choosing SELECT again displays End Test? where SELECT stops the test and the unit goes back to normal operation. If the unit is scrolled to another DLCI and another test is enabled, the unit stops the test on the existing DLCI and starts the new DLCI. Pressing SCROLL takes the unit to the previous performance screen.

The SOS message is displayed as shown in Figure 4.4. This allows the user to view the local and remote DLCI and unit ID numbers for fault isolation. As new circuits are added, information is displayed as shown in Figure 4.4.

TXCC Clock

This is u sed to en abl e or disable generation of the TXCC clock from the unit to the DTE.

DTE Data

In the invert mode, transmit and receive data are inverted at the port interface. This function can be used as a means of guaranteeing ones density when the data is composed of SDLC- type protocols. The default setting is normal

CTS

Setting this field to Forced On allows the forcing of the port control lead output state. Normal allows for normal operation where CTS follows the transition of RTS.

CTS Delay

This field allows setting the delay from when RTS is asserted to when CTS is asserted. T he dela y ranges from 000 to 255 milliseconds in one-millisecond increments. Setting this field to 000 means RTS and CTS are asserted simultaneously.

DCD

Setting this field to Forced On allows the forcing of the port control lead output state. Normal allows for normal operation.

DSR

Setting this field to Forced On allows the forcing of the port control lead output state. Normal allows for normal operation.

Channels Assigned

Selects whet her the channel assign ment are made as a CON T (contiguous) group or as ALT (alternate) channels. Alternate channel mode assigns an idle channel following each data channel. For example, data is carried on channels 1, 3, 5, and 7. Channels 2, 4, 6, and 8 are idle (the idle setting is binary code

01111111). The advantage of alternate channel assignment is that T1 ones density requirements are maintained by the idle channels rather than placing any restrictions on the high-speed data but reduces the available bandwidth from 1.536 kbps to 768 kbps.

34 DDS CSU/DSU and T1 CSU/DSU and FrameStart FSE

Start Channel

The starting channel in the 24 - channel DS1 bit stream must be selected in this field. The unit then assigns the following channels automatically according to the number of channels (#Channel) and the mode selected in Channels Assigned. The choices are 01 through 24.
