Introduction

The MAX TNT has 4 V.35 serial ports, which can be used for nailed Frame Relay connections. The SWAN card can support up to 40 Frame Relay PVCs. The A serial WAN port provides a V.35/RS-449 WAN interface that is typically used for connecting to a Frame Relay switch. The clock speed received from the link determines the serial WAN data rate. The maximum acceptable speed is 8 Mbit/s. The clock speed at the serial WAN port has no effect on the bandwidth of other WAN interfaces in the MAX.

The MAX TNT Serial WAN (SWAN) card is illustrated in Figure 10-1.

Figure 10-1. SWAN card

Installing the SWAN card

You install SWAN cards in the same way you install other MAX TNT slot cards. For instructions, see Installing a slot card.

Connecting the MAX TNT serial WAN line to the WAN

To connect the SWAN card to the WAN:

Using the Ascend Serial WAN cable (part number 2510-0260-xxx, where xxx are digits subject to change), connect the 60 pin D connector to the SWAN card.
Connect the other end to the V.35 port on a Frame Relay switch or to your WAN interface.

Figure 10-2. Connecting the SWAN card to the WAN

Inform your service provider that the equipment is connected, so they can bring up the line.

Reading the SWAN card status light

The SWAN card has a single status light. It is yellow while the card is powering up or in the event of a failure. It is off when the card is operating normal.

Overview of SWAN configuration

Table 10-1 lists the sections describing common tasks you might have to perform to configure a SWAN line. The table includes a brief description of each task, and lists the parameters you will use.

For complete information about the associated parameters, see the MAX TNT Reference Guide.

Understanding SWAN card configuration requirements

Table 10-2 provides important configuration information you may need before configuring your SWAN card.

Table 10-2. SWAN card configuration


Element	Explanation
Connections	The SWAN card currently supports only nailed Frame Relay connections.
Call routing information	Call routing information for the SWAN card is currently ignored.
Trunk groups	Trunk groups are not currently implemented for the SWAN card.
Activation	The Activation parameter tells the MAX which signals control the data flow through the serial WAN port. The DCE to which the serial WAN port is connected (for example, a Frame Relay switch) determines how to set the serial WAN port Activation value. Flow control is always handled by the CTS (Clear To Send) signal. Currently, the Activation parameter supports only one value: of Static.

Making a profile the working profile

When the MAX TNT system detects that SWAN card has been installed, it creates a default SWAN profile for each of the lines on the card.

In the following display example, the Dir command shows default SWAN line profiles created for a card installed in slot 2:

admin> dir SWAN
   305  12/11/1996 15:58:20  { shelf-1 slot-2 1 }
   305  12/11/1996 15:58:20  { shelf-1 slot-2 2 }
   305  12/11/1996 15:58:20  { shelf-1 slot-2 3 }
   305  12/11/1996 15:58:20  { shelf-1 slot-2 4 }

By default, the line is not enabled, which means that it is not available for use. Its default signaling method is inband, typically used for channelized connections.

To configure a SWAN profile, make it the working profile by reading it into the edit buffer. For example:

admin> read SWAN {1 2 1}
SWAN/{ shelf-1 slot-2 1 } read

Once you have read in a profile, it remains the working profile until you read in another profile.

To save your configuration changes, use the write command. For example,

admin> write
SWAN/{ shelf-1 slot-2 1} written

To list the parameters in a SWAN profile, use the List command, as in the following example:

admin> list
name = ""
physical-address* = { any-shelf any-slot 0 }
enabled = no
line-config = { 0 0 static { any-shelf any-slot 0 } }

Following is an example of a SWAN profile, with its parameters set to sample values:

SWAN { shelf-N slot-N N }
name = 1:14:2
physical-address* = { shelf-1 slot-14 2 }
enabled = no
line-config 
      trunk-group = 0
      nailed-group = 2
      activation = static
      call-route-info 
            shelf = any-shelf
            slot = any-slot
            item-number = 0

Assigning a name to Serial WAN profiles

In a SWAN profile, the Name parameter enables you to assign the profile a name of up to 16 characters. By default, the name displays the address of the card as shelf:slot:item. Note that the MAX TNT uses only the physical-address to identify the serial WAN line.

The name is displayed after the line's physical address in the Dir command output. For example:

admin> read SWAN {1 12 0}
admin> set name = SWAN1 
admin> write
SWAN/{ shelf-1 slot-12 0 } written
admin> dir SWAN
17  04/17/1997 19:00:02  { shelf-1 slot-12 0 }  "SWAN1"

For serial WAN lines, the Line Status window displays the first eight characters of the name if one has been assigned. If the name is longer than eight characters, the last character displayed is a plus-sign (+).

Enabling a line

By default each serial WAN line is disabled. To enable a serial WAN line, read its profile to make it the working profile, then set Enable to Yes, as in the following example:

admin> read SWAN {1 2 1}
SWAN/{ shelf-1 slot-2 1 } read
admin> set enabled = yes
admin> write
SWAN/{ shelf-1 slot-2 1 } written

Specifying a nailed group

The Nailed-Group parameter assigns a nailed group number to the serial WAN line. The setting, which must also be specified in a Frame Relay profile, directs the Frame Relay connection to use this line.

To specify a nailed group, proceed as in the following example:

admin> read SWAN {1 2 1}
SWAN/{ shelf-1 slot-2 1 } read
admin> set line nailed-group= 5
admin> write
SWAN/{ shelf-1 slot-2 1 } written

Sample serial WAN configuration

This section provides an example of how to configure a SWAN card. Refer to the MAX TNT Network Configuration Guide for complete information about configuring the MAX TNT serial WAN lines.

The general steps involved in configuring a SWAN card are:

Configure the SWAN card itself
Configure a Frame Relay profile
Configure a Connection profile

Configuring the SWAN card

The following example illustrates the procedure for configuring a SWAN card installed in shelf 1, slot 15:

Open the SWAN profile and list its contents.

admin> read swan { 1 15 4 } 
SWAN/{ shelf-1 slot-15 4 } read

admin> list
name = 1:15:4
physical-address* = { shelf-1 slot-15 4 }
enabled = no
line-config = { 0 0 static { any-shelf any-slot 0 } }

Enable the line.

List the Line-Config subprofile.

admin> list line-config
trunk-group = 0
nailed-group = 0
activation = static
call-route-info = { any-shelf any-slot 0 }

Assign a nailed-group number. This number will be referenced in a Frame-Relay profile to direct the datalink to use this line.

Write the profile.

admin> write
SWAN/{ shelf-1 slot-15 4 } written

Configuring the Frame Relay profile

This section shows how to create a Frame-Relay profile that uses the example serial WAN line configured in the preceding section. For more details of Frame-Relay configuration, see the MAX TNT ISP & Telecommuting Configuration Guide.

To configure the Frame Relay profile:

Create a new Frame-Relay profile and list its contents:

admin> new frame frswan1
FRAME-RELAY/frswan1 read

admin> list
fr-name* = frswan1
active = no
nailed-up-group = 32769
nailed-mode = ft1
called-number-type = 2
switched-call-type = 64k-clear
phone-number = ""
billing-number = ""
transit-number = ""
Link-Mgmt = none
call-by-call-id = 0
n391-val = 6
n392-val = 3
n393-val = 4
t391-val = 10
t392-val = 15
MRU = 1532
fr-type-val = dte
dceN392-val = 3
dceN393-val = 4
fr-Link-Up = no

Activate the datalink:
Specify the serial WAN line's nailed-group value in the Nailed-Up-Group parameter. The two values must match:
Write the Frame-Relay profile:

Configuring the Connection profile

To configure a Connection profile that makes use of the nailed Frame-Relay link:

Create a Connection profile and list its contents.

admin> new conn m41
CONNECTION/m41 read

admin> list
station* = m41
active = no
encapsulation-protocol = mpp
called-number-type = national
dial-number = ""
clid = ""
ip-options = { yes yes 10.5.249.154/29 0.0.0.0/0 7 100 255 no no 0 0.0.+
bridging-options = { 0 no }
session-options = { "" "" no 120 no-idle 120 "" 0 }
telco-options = { ans-and-orig no off 1 no no 56k-restricted 0 "" "" no +
ppp-options = { no-ppp-auth "" "" stac 1524 no 600 600 }
mp-options = { 1 1 2 }
mpp-options = { "" quadratic transmit 1 1 15 5 10 70 }
fr-options = { "" 16 "" no "" 16 }
tcp-clear-options = { "" 0 no "" 256 20 }
usrRad-options = { global 0.0.0.0 1646 "" 1 acct-base-10 }
calledNumber = ""

Activate the profile and specify Frame Relay encapsulation:

admin> set active = yes

admin> set encapsulation = frame-relay

List the FR-Options subprofile:

admin> list fr-options
frame-relay-profile = ""
dlci = 16
circuit-name = ""
fr-direct-enabled = no
fr-profile = ""
fr-dlci = 16

Specify the name of the Frame-Relay profile that uses the serial WAN line:
Assign the appropriate DLCI:
Write the profile:
