4.352 ent-slk
Use this command to add a low-speed or high-speed (ATM or IP) signaling link to a linkset in the database.
Signaling links are the only elements in the database directly supported by a hardware device. When a link is added to a linkset, the link remains in the state OOS-MT-DSBLD (out of service maintenance disabled) until it is activated.
For E5-E1T1-B cards, use this command to associate a signaling link and a timeslot with the E1, T1 or J1 interface that will service the timeslot.
For E5-E1T1-B cards used for SE-HSL links, use this command to assign links A and B on any 2 of the 8 E5-E1T1-B card ports.
Up to 64 signaling links can be assigned to one E5-E1T1-B card, allowing links A, A1 - A31, B, and B1 - B31 to be provisioned.
Up to 128 signaling links can be assigned to SLIC cards running IPSG application, allowing links A, A1 - A63, B, and B1 - B63 to be provisioned.
Up to 3 signaling links can be assigned to an E5-ATM-B card, allowing links A, A1, and B to be provisioned.
Note:
The link parameter has been added as a synonym for the port parameter. Either port or link can be used for a few more EAGLE releases; then the port parameter will be removed.Parameters

The MTP Level 2 timers (l2tset parameter) are not valid for IP links or for ATM links.
A link is equipped when it is physically operational, that is, when the hardware is in place that is needed to support the link.
Signaling Links for E5-E1T1-B Cards
An E5-E1T1-B card can be used for E1, T1, or J1 card functions, but not both at the same time. E1 cards and T1 cards can coexist in the same EAGLE.
Each signaling link for an E1, T1, or J1 card must be associated with a timeslot assigned in this command. Each signaling link and timeslot assigned for an E1, T1, or J1 card must be associated with an E1, T1, or J1 interface that has been defined for one of the ports on the card (see the ent-e1 or ent-t1 command, respectively).
Timeslots and signaling links are defined in the ent-slk command by a combination of card location (loc parameter), the signaling link that uses the timeslot (A, A1-A31, B, B1-B31), the timeslot number (ts), and the port for the servicing E1, T1, or J1 interface on the E1, T1, or J1 card (e1port or t1port parameter). Timeslot numbers must be unique to the E1, T1, or J1 interface that services the timeslot; that is, the same timeslot cannot be assigned to the same E1, T1, or J1 interface for more than one signaling link.
Each E5-E1T1-B card used as an E1 card can have up to 64 signaling links assigned to the card. Each E1 interface on the card can service 1-31 timeslots.
Each E5-E1T1-B card used as a T1 card can have up to 64 signaling links assigned to the card. Each T1 interface on the card can service 1-24 timeslots.
Each E5-E1T1-B card used as a J1 card can have up to 64 signaling links assigned to the card. Each J1 interface on the card can service 1-24 timeslots.
Signaling Links for E5-ATM-B Cards
An E5-ATM-B card can support E1 or T1 card functions: however, the card cannot support both functions at the same time. Cards running E1 and T1 functions can coexist in the same EAGLE.
Each E5-ATM-B card can have up to 3 signaling links assigned to the card. Only the A, A1, or B link can be used. The card must be inhibited, a 3 Links per Card feature quantity must be enabled, and the value specified for the vci parameter must be less than or equal to 16383 before the A1 link can be provisioned.
The A, A1, and B links can be provisioned for a location if a card is not seated in that location. However, if a card other than an E5-ATM-B card is inserted in this location, then the card is auto-inhibited.
Signaling Links for IPSG Cards
An IPSG card supports both M2PA and M3UA signaling links.
The E5-ENET-B card supports up to 32 signaling links per card, 16 M3UA links per association, and 32 associations per card.
The SLIC card supports up to 128 signaling links per card, 16 M3UA links per association, and 128 associations per card.
Multiple M3UA signaling links with routing context (different linksets/AS, up to 16) can use a single association.
Each M3UA AS-ASP instance maps to a signaling link. Signaling link state depends upon AS-ASP state, as well as administrative action.
The IPSG card can share M2PA linksets with IPLIMI, and IPLHC cards, but the card cannot share M3UA linksets with SS7IPGW, IPGWI, and IPGHC cards.
The IPSG card supports ANSI and ITU and ITUN/ITUN24 signaling links simultaneously on one card and on one association. Each signaling link resides in a set of networks determined by the APC and SAPCs of the assigned linkset.
The slktps parameter specified for the IPSG linkset (see the ent/chg-ls command) specifies the TPS for each link provisioned for that linkset.
HSL and LSL in same linkset
Mixing of high speed links and low speed links in a linkset is supported for migration purposes and is not recommended for standard provisioning.
Signaling links and scheduled UI measurement reports
If the Integrated Measurements feature is turned on, then the measurements subsystem automatically disables the scheduled UI measurements reports, including the daily scheduled reports, if the entered link causes the provisioned link count to exceed 700.
