historically as an RMON2 User History object.

Frame Relay Traffic P o li cing.



Ensures proper alignment and correlation of
CIR (Committed Information Rate) values between the Fram eS aver unit and
the network switch. When this feature is enabled, the unit can enforce CIR and
EIR (Excess Information Rate), marking frames that exceed CIR as DE
(Discard Eligible) using the same method used by the switch.

Service P rovider S upport.



Provides information and tools useful to network

service providers, which includes the following:
— IP Routing Table – Shows the IP routing table for the FrameSaver unit,

with network as well as host routes, the number of hops to the destination,
the method by which the route was added to the table, the interface used
to get to the destination, and how long the route has been in existence.

— Tr ap Event Log – Displays the SNMP (Simple Network Management

Protocol) trap event log for the F rameSav er unit fr om the menu-driven user
interface, with the most recent events first, keeping a running total for all
trap events stored, the amount of time since the event was logged, plus a
description of the trap.

— Troubleshooting PVC – Provides a dedicated troubleshooting

management link that helps service providers isolate problems within their
network.

AT M VPI/VCI and DLCI Correlation.



For networks with both ATM and frame
relay-access endpoints, allows the FrameSaver unit to report the origina ting
Virtual Path and Channel Identifier (VPI/VCI) in the far-end ATM-access
endpoint where the local DLCI is mapped so they can be correlated for
OpenLane SLV reports.

Dual Flash Memory.



Allows software upgrades while the unit is up and
running. Two software loads can be stored and implemented at the user’s
discretion.

format to share the T1 network with other high-speed equipment so that voice
traffic can share the same local access circuit as the frame relay data.

Back-to-Back Operation.



Allows two FrameSaver devices to be connected
via a leased-line network or simulation so a point-to-point configuration can be
implemented.

Enhanced Ping Operation.



FrameSaver devic es can check connectivity and
roundtrip response time to any remote device in either direction, via the
FrameSav er internal management network or the data path.

Payload Management.



Any standard, non-management DLCI can be
designated as payload managed, providing management directly from a user
data PVC, and support for Telnet, ping, SNMP, and FTP.

Optional ISDN Backup.



FrameSaver SLV 9126 and 9126-II CSU/DSUs can
be equipped with a BRI DBM, which supports up to two channels. The
channels may have different destinations. The DBM may be field-installed in
the FrameSaver SLV 9126 CSU/DSU, and must be factory-installed in the
9126-II CSU/DSU.

FrameSaver SLV 9128-II 1-slot units can be equipped with a PRI DBM, which
supports up to 23 B-channels, or a BRI DBM. Carrier-mounted FrameSaver
SLV 9128-II NAMs support a PRI DBM only.

When an ISDN BRI or PRI DBM (Basic Rate Interface or Primary Rate
Interface Dial Backup Module) is installed, the following ISDN backup features
are provided:

— Provides automatic dial backup through the ISDN for data when primary

frame relay network or access line failures occur, then automatically
restores data to the primary route when service returns to normal. Backup
is supported regardless of whether or not Caller ID is provisioned on the
ISDN circuit. A secondary backup phone number is also available to call
when a backup link cannot be established with the primary backup site.

— Supports simultaneous origination, answering, or origination and

answering backup calls, as needed, based upon how the ISDN Link
Profile is set up. This feature is also known as peer-to-peer calling.

— Provides automatic configuration of an alternat e route and DLCI for

automatically created PVCs at either the remote site or central site based
upon the learned far-end DLCI number. When the automatic backup
feature is enabled, backup and restoration occur automatically.

— Provides backup timers that can be configured to better control the

amount of time required before backup is initiated, when a backup call will
be terminated once the failure condition clears, and a delay before normal
service is restored. These features are useful during periods of frequent
service disrup tion.

In addition, round trip latency thresholds can be configured that will initiate
backup when configured thresholds are exceeded.

— Supports backup call groups, where redundant PVCs can be assigned to

a specified call group. Using this feature, the unit only goes into backup
when
soon as

PVCs in the group are down, and it returns to norm al service as

all

PVC in the group is operational again. This feature is useful

one

when multiple PVCs are going to redundant central sites.

— When the SLV Sample Interval is set to 10 seconds, provides advance

detection of network problems before a DLCI Down indication is received,
to minimize data loss.

— Provides customer premises equipment (CPE ) with a Backward Explicit

Congestion Notification (BECN) when backup bandwidth is not sufficient
for the traffic, allowing the CPE time to slow traffic to the ISDN before the
network starts discarding data.

— Supports Frame Relay Forum Multilink Frame Relay Implementation

Agreement – FRF.15 so backup bandwidth can be increased by
aggregating multiple B-channels over the ISDN link.

— Supports collection of call and call attempt statistical information that can

be viewed from the menu-driven user interface or via SNMP, and supports
alarm generation and call security, as well.

— Provides test call capability on ISDN backup links so ISDN and DBM

function can be verified before there is an actual primar y link failure and
switched over to the backup link. Periodic tests are recommended, which
can be performed from the menu-driven user interface, or through SNMP
commands. Multiple Last Cause Values are also provided to assist in
troubleshooting ISDN problems.

Setting Up the Modem

The unit has an internal modem for dial-in access to the menu-driven user
interface, as well as dial-out capability when an SNMP trap is generated. When the
modem will be used to dial out, Modem Directory phone numbers need to be set
up. Otherwise, simply configure or change dial-in access to the unit.

The modem port is already configured for connection to an asynchronous terminal
and dial-in access, with Port Use set to Ter m ina l. However, additional changes
may be needed (see Table 4-25, Modem Port Options).

For dial-in access to the menu-driven user interf ace via Telnet, make sure P ort Use

Setting Up to Use the Modem PassThru Feature

Dial-in access to the router is possible via the Modem PassThru feature, also
known as the Router Assist feature. The FrameSav er unit’s COM port must be
connected to the router’s auxiliar y (AUX) or co ns o le p ort, and the C O M p ort must
be configured for this use.

When this feature is set up and active, a logical connection between the unit’s
modem and COM por ts is made, and data received over the modem port is
transmitted out the COM port to the router’s A UX or console port. When an escape
sequence (minus, minus, minus, with a minimum of 50 ms between each) is
detected, the FrameSaver unit switches back to normal user interface operation.

Selecting a Frame Relay Discovery Mode

When a Frame Relay Discovery Mode is active, the FrameSaver unit “discovers”
network DLCIs from the network LMI status response message. It configures a
network DLCI and a user data port DLCI, and automatically connects them to
create a PVC.

Main Menu→Auto-Configuration→Frame Relay Discovery Mode

Automatically configured network DLCIs are multiplexed, and each automatically
configured port DLCI carries the same DLCI Number as its corresponding network
DLCI. These are the same DLCI numbers that would have been available had the
FrameSaver unit not been inserted in the link, between your equipment and the
network.

NO TE:

A local Management PVC (e.g., the PVC between the router and the
FrameSav er unit’s user data port) must be configured manually.

network side are IP Enabled (not standard or multiplexed) DLCIs. In addition,
payload management is configured for the network DLCI and assigned the Node

terminated and the data is returned to the primary data path regardless of the
primary path’s condition.

You can restrict auto backup to occur only:

On certain days of the week

The following additional features can be configured:

Delays can be configured to control how long the unit will wait before initiating



backup when a DLCI is declared down, and how long it will wait to restore
service once the DLCI is declared operational again.

A threshold can be set to determine how many times a primary destination

control traps can be sent to trap manager(s).

See Table 4-22, SNMP Traps and Trap Dial-Out Options, for configuration
information.

Assigning DLCIs to a Backup Group

DLCIs can be assigned to a Backup Group to reduce backup charges when

Port-2_Follows_Net1-FR1 – React s like the Port- 1_Follows_Net 1-FR1 selection, but for
Port-2 instead.

Rtr-S0_Follows_Net 1-FR1 – Brings LMI down on Rtr-S0 when LMI on the network
interfa ce goes do wn, disab li ng Rtr- S0. Wh en LMI on t he network int er fa ce co mes bac k up,
Rtr-S0 is reenabled. The LMI state on Rtr-S0 has no effect on the LMI state on the
network interf ace. That is, Rtr-S0’s LMI follows the network interface’s LMI.

All_Ports_Follow_Net1-FR1 – Brings LMI down on all user data ports when LMI on the
network interface goes down, disabling all ports and deasserting their control leads.
Allows LMI t o come back up and reenabl es the ports when LMI comes up on the network.
That is, LMI on each port follows the network interface’s LMI. The stat e of LMI on the port
will not affect the state of LMI on the network interface.

Port-1_Codependent_with_Net1-FR1 – Brings LMI down on the network interface whe n
LMI on P ort- 1 goes down (or LMI down on Port-1 when LMI on the network interface goes
down), and allo ws LMI to come back up when LMI comes back on t he other interface.
That is, the LMI state for one interface is dependent on the other. Use thi s setting when
backup is thr ough the r outer i nstead of the unit . It is
isolation more dif fi cult.

Port-2_Codependent_with_Net1-FR1 – Reacts like the
Port-1_Codepende nt_with_Net 1-FR1 selection, but for Port-2 instead. The state of LMI on
the network interface will not aff ect the state of LMI on Port-1.

Rtr-S0_Codependent_with_Net1-FR1 – Brings LM I do wn on the net work int erf a ce when
LMI on Rtr-S0 goes down (or LMI down on Rtr-S0 when LMI on the network interface

and received on the interface, and the LMI for a PVC connection will become active when
the link is required. If thi s profile is configur ed as the alternate link and the primary link or
DLCI fails, the unit dials the Outbound Phone Number, or the Alternate Outbound Phone

Assigning Time Slots/Cross Connections

The Time Slot Assignment/Cross Connect feature provides an easy method of
assigning time slots for frame relay data and creating cross-connections to the
synchronous data interface. The system allows you to assign DS0s on the T1
network interface and between the user data port and network interface in order to
share the T1 network.

You can also clear cross-connection assignments for the system, or for a selected
slot or interface.

Assigning Frame Relay Time Slots to the Network Interface

Before assigning network time slots for use by frame relay traffic, configure the
Network physical and Frame Relay options (if needed), then allow Time Slot
Discovery to autodetect and assign the appropriate time slots to frame relay.

If there are multiple Frame Relay data links on the network interface , or if Time Slot
Discovery is not currently active, you can manually assign time slots on the
network interface for frame relay traffic using the Frame Relay Network
Assignments screen. This screen is read-only when Time Slot Discovery is set to
Enable for the network interface.

Only those DSX-1-to-Network assignments from page 1 are displayed on this
page, from left to right and top to bottom in ascending order, by network and time
slot.

When a CGA condition (LOS, OOF, or AIS) is declared for a T1 interface, the
signaling bits being transmitted to the other T1 interface for the DS0 are forced to
idle for two seconds (except for user-defined patterns which are transmitted
immediately). This drops any call in progress. The signaling bits are then forced to
the selected state (Busy or Idle), and remain in this state until the CGA condition
clears. At this point, the received signaling bits from the T1 interface which
formerly had the CGA condition are passed through to the other T1 interface.

NO TE:

Trunk conditioning will only occur on DS0s that are cross-connected to
another T1 interface. All other DS0s remain unaffected by trunk conditioning.

Enter one of the values shown in Table 4-12, Signaling and Trunk Conditioning

Values, in each of the fields on both the Network side and the DSX-1 side.

Although you can choose any value for the DSX-1 side, the default value displayed
is based on a typical setting that would be used with the corresponding Network
side value. Typical pairs of values are shown in the table below . If you change the
Network side value, the DSX side value is changed to the corresponding default
value.
