4.629 tst-slk

Use this command for testing signaling links.

  • The loopback parameter on the tst-slk command provides the ability to select from among the following loopback tests: local transceiver (lxvr), oam, line, payload, and either low-speed signaling links or ATM high-speed signaling links (sltc).

  • The command is not valid on E5-ENET-B cards with SS7IPGW and IPGWI links.
  • For low-speed links, LXVR and SLTC tests are allowed.
  • For E5-ATM-B cards, the LXVR, SLTC, PAYLOAD, LINE, and OAM tests are allowed.
  • For E5-ENET-B cards with IPLHC links, the SLTC test is allowed.
  • For E5-E1T1-B cards, only the SLTC test is allowed. 
  • For E5-ENET-B or SLIC cards running the IPSG application, the command is only supported for IPSG-M2PA signaling links, and the SLTC test is allowed.

See Summary of Loopback Testing Commands and Functions in Appendix A.

Parameters

link (mandatory)
The signaling link on the card specified in the loc parameter. The links can be specified in any sequence or pattern.
Synonym:
port
Range:
a, b, a1 - a63, b1 - b63

Not all card types support all link parameter values.

See Table A-1  for valid link parameter range values for each type of card that can have a location specified in the loc parameter.

loc (mandatory)
The card location as stenciled on the shelf of the system.
Range:
1101 - 1108, 1111 - 1112, 1201 - 1208, 1211 - 1218, 1301 - 1308, 1311 - 1318, 2101 - 2108, 2111 - 2118, 2201 - 2208, 2211 - 2218, 2301 - 2308, 2311 - 2318, 3101 - 3108, 3111 - 3118, 3201 - 3208, 3211 - 3218, 3301 - 3308, 3311 - 3318, 4101 - 4108, 4111 - 4118, 4201 - 4208, 4211 - 4218, 4301 - 4308, 4311 - 4318, 5101 - 5108, 5111 - 5118, 5201 - 5208, 5211 - 5218, 5301 - 5308, 5311 - 5318, 6101 - 6108, 6111 - 6118
action (optional)
Indicator of command action to stop or start a test.
Range:
start
stop
Default:
start
force (optional)
Range:
yes
no
Default:
no
loopback (optional)
The type of loopback test to run
Range:
line
This test is similar to the payload loopback test, but the data transmitted to the remote system is received by the remote system’s ATM driver.
lxvr
Loopback at the local transceiver without involving the remote STP. For the ADS0, AINF, AOCU, and AV35 appliques, the MTP-2 protocol stack and ISCC hardware are tested. For AATM applique and DS1 interface, the AATM hardware, ATM level 2 protocol stack, and AAL5CP portion of ATM driver are tested,
oam
Messages are passed between local and remote systems to guarantee that the ATMM portion of ATM driver is functioning.
payload
This test is similar to the local transceiver loopback test. The wire is also tested because the loopback is at the remote’s DS1 interface instead of the local’s DS1 interface.
sltc
This test can be run on either the low-speed signaling links or the ATM high-speed signaling links. This is the only test that is supported for m2pa links on IPLHC cards.
Default:
sltc
time (optional)
The time duration for testing the link.
Range:
1 - 240000

hhmmss

hh=hours ( 00-24)

mm=minutes (00-59)

ss=seconds (00-59)

For example, time=1 or time=000001 is one second; time=240000 is 24 hours; time=200 or time=000200 is 2 minutes.

Default:
1

Example

tst-slk:loc=1203:link=a

tst-slk:loc=1203:link=a:loopback=lxvr

tst-slk:loc=1205:link=b:time=000200:force=yes:action=start

tst-slk:loc=1205:link=b:action=stop

tst-slk:loc=1205:link=b:time=200

Dependencies

The card in the location indicated by the loc parameter must already be equipped.

A card location that is valid and defined in the database must be specified.

  • A card location equipped with an E5-APP-B card cannot be specified.
  • A card location equipped with a Telco Switch cannot be specified.

If the signaling link is an ATM HSL signaling link, only the link=a parameter can be specified.

This command is not supported for cards running the IPGHC application.

The payload and line values are not valid for the loopback parameter when the card is an E1 ATM.

Only the SLTC test can be run on card types LIME1 and LIMT1.

The card must contain the specified signaling link.

The specified signaling link must be provisioned in the database.

The specified signaling link must be an SS7 signaling link.

The signaling link that is used for LFS (Link Fault Sectionalization) testing cannot be active.

A previously entered command for a link test must be accepted before another link test command can be entered.

This command cannot be entered if the LFS test is running on the specified link.

The specified link cannot be in Command Driven Loopback (CDL) when this command is entered. The link must be removed from CDL before this command can be entered for the link. (See the act/dact-cdl commands).

The force=yes parameter must be specified to start a test when 256 or more tests are already running in the system.

This command cannot be entered if the maximum number of LFS or link tests are already running in the system. At least one active test must complete before the command can be entered again.

Only one link test can be running on a signaling link at one time.

The action=stop parameter cannot be specified when there is no active link test running on the specified link.

When the action=stop parameter is specified, the loopback, time, and force parameters cannot be specified.

If an IPSG-M3UA signaling link is used, then this command cannot be entered.

If an IPSG-M2PA signaling link is used, the loopback=sltc parameter must be specified.

The card must be equipped and in service, and must be one of the following cards:

  • E5-E1T1-B card running the SS7ANSI or CCS7ITU application
  • E5-ATM-B card running the ATMANSI or ATMITU application
  • E5-ENET-B card running the IPLHC or IPSG application
  • SLIC card running the IPSG application

Notes

The lxvr and sltc loopback tests can be run on low-speed signaling links. All the loopback tests can be run on the ATM high-speed signaling links.

Output

If the card is inhibited (not in service), this message appears when a link test is attempted:
