This procedure is used to add an E1 signaling link to the database using the ent-slk
command and these parameters.
:loc
– The card location of the card that the E1 signaling link will be assigned to.
:link
– The signaling link on the card specified in the loc
parameter.
:lsn
– The name of the linkset that will contain the signaling link.
:slc
– The signaling link code. The SLC must be unique within the linkset. It must be the same at both the EAGLE location and the distant node.
:bps
– The transmission rate for the link in bits per second.
:ecm
– Error correction method, either basic
or pcr
. The default value for this parameter is basic
.
:pcrn1
– The threshold of the number of MSUs available for retransmission. If the error correction method being used is PCR (:ecm=pcr
), and this threshold is reached, no new MSUs or FISUs are sent. The retransmission cycle is continued up to the last MSU entered into the retransmission buffer in the order in which they were originally transmitted.
:pcrn2
– The threshold of the number of MSU octets available for retransmission. If the error correction method being used is PCR (:ecm=pcr
), and this threshold is reached, no new MSUs or FISUs are sent. The retransmission cycle is continued up to the last MSU entered into the retransmission buffer in the order in which they were originally transmitted.
:ts
– The timeslot on the E1 card or channel card being used for the E1 signaling link.
:e1port
– The E1 port on the E1 card that is servicing the timeslot selected for the E1 signaling link.
:e1loc
– The location of the E1 card servicing the timeslot selected for the E1 signaling link. This parameter can be specified only when provisioning E1 signaling links on channel cards.
:l2tset
– The level 2 timer set table assigned to the E1 signaling link. The type of linkset the E1 signaling link is assigned to and the E1 card’s application determines the value of the l2tset
parameter. The level 2 timer set tables are defined in Changing Level 2 Timers .
The ent-slk
command contains other optional parameters that can be used to configure a signaling link. These parameters are not shown here because they are not necessary to provision an E1 signaling link. These parameters are explained in more detail in Adding an SS7 Signaling Link, or in the ent-slk
command description in Commands User's Guide.
These items must be configured in the database before an E1 signaling link can be added:
Shelf – see Adding a Shelf in Database Administration - System Management User's Guide
lime1
) or ChannelCard (card type limch
) running either the ss7ansi
or ccs7itu
applications – see Adding a LIM-E1 Card procedureVerify that the link has been physically installed (all cable connections have been made).
Timeslot 16 (ts=16
) cannot be specified for an E1 signaling link if the E1 interface servicing this link has CAS enabled. This is shown by the entry on
in the CAS
field of the rtrv-e1
output.
If the E1 signaling link is assigned to a channel card (card type limch
), the e1port
parameter cannot be specified. The e1port
parameter value defaults to 1.
All E1 signaling links in a linkset can use either the 56000 or 64000 transmission rate. The transmission rate for the E1 signaling links in the linkset do not have to be the same.
The values for the ts
parameter must be from 1 to 31.
The linkset must be in the database. The number of signaling links in a linkset cannot exceed 16. This can be verified with the rtrv-ls
command.
The APC of the linkset assigned to the signaling link must be in the SS7 domain. Use the rtrv-dstn
command to verify the domain of the APC of the linkset.
The pcrn1
or pcrn2
parameters can only be specified if the ecm=pcr
parameter is specified.
If the E1 signaling link is being assigned to an unchannelized E1 port (shown by the entry UNCHAN
in the LINKCLASS
field in the rtrv-e1
output), you cannot specify the ts
parameter. An E1 signaling link containing an unchannelized E1 port can be assigned only to an HC-MIM or an E5-E1T1 card. A maximum of two E1 signaling links containing an unchannelized E1 port can be assigned to an HC-MIM. The link
parameter value for these links must be either a
or b
. A maximum of one E1 signaling link containing an unchannelized E1 port can be assigned to an E5-E1T1 card. The link
parameter value for this link must be a
. The transmission rate (bps
parameter) for an unchannelized E1 signaling link is 1984000 bits per second. The bps
parameter is optional, and if not specified with the ent-slk
command, the bps
parameter value defaults to 1984000 bits per seconds.
If the E1 signaling link is being assigned to a channel bridged E1 port (shown by the entries MASTER
or SLAVE
in the CHANBRDG
field in the rtrv-e1
output), the E1 port value for the signaling link must be the odd numbered ( MASTER
) E1 port.
If the E1 card is not an HC-MIM or an E5-E1T1 card, a maximum of 2 or 8 E1 signaling links can be assigned to the card. The range of link
parameter values is dependent on the type of E1 card the signaling link is assigned to. If the E1 card is an E1/T1MIM, the link
parameter values are A - A3, or B - B3, allowing a maximum of 8 signaling links on the card.
If the E1 signaling link is being assigned to a channelized E1 port (shown by the entry CHAN
in the LINKCLASS
field in the rtrv-e1
output) on an HC-MIM, the link
parameter values are A - A31 or B - B31. An HC-MIM can contain a maximum of 64 channelized E1 signaling links. If signaling links A16 to A31, or B16 to B31 will be assigned to the card, the FAN feature must be turned on. The status of the FAN feature is shown in the rtrv-feat
command output. The shelf containing the HC-MIM being added in this procedure must have fans installed. If the fans are not installed on the shelf containing the HC-MIM, go to Installation Guide and install the fans.
If the E1 signaling link is being assigned to a channelized E1 port (shown by the entry CHAN
in the LINKCLASS
field in the rtrv-e1
output) on an E5-E1T1 card, the link
parameter values are A - A15 or B - B15. An E5-E1T1 card can contain a maximum of 32 channelized E1 signaling links.
To configure the EAGLE to perform circular routing detection test on the signaling links, perform the Configuring Circular Route Detection procedure.
Note:
Circular route detection is not supported in ITU networks.To provision a EAGLE with more than 1200 signaling links, the EAGLE must have certain levels of hardware installed. See the Requirements for EAGLEs Containing more than 1200 Signaling Links section for more information on these hardware requirements.
The EAGLE can contain a mixture of low-speed, E1, T1, ATM high-speed, and IP signalling links. The Determining the Number of High-Speed and Low-Speed Signaling Links section describes how to determine the quantities of the different types of signaling links the EAGLE can have.
Configuring Signaling Links on LIM-E1 Cards
The main consideration for the provisioning of LIM-E1 cards into the EAGLE is to determine the number of LIM-E1 cards existing in the network and the equipment needed for expanding the signaling link capacity of the EAGLE. To utilize the flexibility of the E1 interface feature, you may want to determine the minimum number of LIM-E1 cards needed to process the total number of SS7 links and then consider diversity for reliability reasons.
Use the following points as guidelines when considering diversity for E1:
As an example, consider a network consisting of 30 LIM-E1 cards with a total number of 100 links where the largest link set size is 8. The most efficient way to provision the EAGLE would be to have 4 extension shelves equipped with the E1 Cabling Backplane, 1 E1Card, and 12 Channel Cards per shelf. Utilizing 1 “B” bus on each shelf, 25 signaling links would be terminated on each shelf for a total of 100. This is also the minimum number of LIM-E1 Cards required for this example.
With the same example but using the third and fifth bullets above as a consideration, the EAGLE would be provisioned with 8 extension shelves equipped with the E1 Cabling Backplane. Four of the shelves would be equipped with 1 E1Card and 6 Channel Cards, and the other 4 shelves would be equipped with 1 E1Card and 5 Channel Cards. Since the largest link set size is 8, a total of 8 LIM-E1 Cards is required. Utilizing 1 “B” bus on each shelf, 13 signaling links would be terminated on each shelf with 6 Channel Cards, and 12 signaling links would be terminated on each shelf with 5 Channel Cards.

Canceling the REPT-STAT-SLK
and RTRV-SLK
Commands
Because the rept-stat-slk
and rtrv-slk
commands used in this procedure can output information for a long period of time, the rept-stat-slk
and rtrv-slk
commands can be canceled and the output to the terminal stopped. There are three ways that the rept-stat-slk
and rtrv-slk
commands can be canceled.

is the terminal where the rept-stat-slk
or rtrv-slk
commands were entered, from another terminal other that the terminal where the rept-stat-slk
or rtrv-slk
commands was entered. To enter the canc-cmd:trm=<xx>
command, the terminal must allow Security Administration commands to be entered from it and the user must be allowed to enter Security Administration commands. The terminal’s permissions can be verified with the rtrv-secu-trm
command. The user’s permissions can be verified with the rtrv-user
or rtrv-secu-user
commands.For more information about the canc-cmd
command, go to the Commands User's Guide.
