Locate the card slots in the modules that house ISDN BRI cards. Group all SILCs, UILCs, BRSCs, superloops and the MISP that supports them in the same network group to avoid using junctors for dedicated connections.

—End—

The following rules apply when selecting the card slots:

MISPs

•

MISPs are inserted into the Core/Network Module for Large Systems (Multi Group). Refer to the LD 22 printout to identify modules with unused network card slots and to Table 2 "ISDN BRI card location"

(page 16) for the card slots in these modules that can house MISPs.

•

An MISP cannot share network loop addresses with a Superloop Network Card in the Large Systems. The MISP requires two network loop addresses and one network card slot.

•

An MISP supports a maximum of 8 BRSCs and two line cards.

•

An MISP supports a set of 4 SILCs or UILCs when not supporting a BRSC.

•

An MISP can support both BRSCs and SILCs or UILCs at the same time. If it serves one BRSC, an MISP can also support three line cards. If it supports two or more BRSCs, an MISP can also support two line cards.

BRSCs

•

Install one BRSC for each IPE module.

•

With a BRSC conﬁgured, an IPE module can support a maximum of 15 line cards. These can be up to eight UILCs combined with any other seven peripheral cards (including SILCs), or up to 15 SILCs.

SILCs/UILCs

•

The cards are installed in the Core/Network Module or the IPE Module for all system options. Refer to the LD 20 printout to identify modules with unused peripheral card slots.

•

In each module, install a maximum of 15 SILCs, or eight UILCs combined with any other seven peripheral cards (including SILCs). If 15 SILCs are installed, the remaining slots in the module may contain a BRSC, a UILCs, or non-ISDN BRI cards that do not need the - 48 V power supply of the IPE module (this restriction is due to power supply limitations for the module). If eight UILCs are used, you may install any other card which could reside in the IPE module.

Each SILC provides eight four-wire full-duplex ports. These ports are connected to building wiring to form DSLs. These ports are polarity-sensitive. Signal polarity must be maintained along each loop.

Each UILC provides eight two-wire full-duplex ports. These ports are connected to twisted pair building wiring to form DSLs. These DSLs are not polarity-sensitive and, although recommended, it is not necessary to maintain signal polarity along each loop.

Procedure 9 Cross-connecting SILC and/or UILC ports to the building wiring

Step Action

Perform the following steps to cross-connect the SILC and/or UILC ports to the building wiring.

Identify the card type (SILC or UILC) for a connector on the MDF. Refer to the IPE or CE module card location form at the end of this chapter, which shows the card type connected to each I/O panel connector.

Identify transmit and receive pairs on the top of the labeled distribution strip for the card type and module type you are connecting. To identify SILC or UILC ports and their pin numbers, refer to Table 5 "NT8D37 IPE moduleSILC and UILC

pair-terminations for connectors A, E, K, R (12-cable conﬁguration)" (page 33) through Table 11 "Card location form: NT8D37 IPE module (12-cable conﬁguration)" (page 44), which begins on Table 5 "NT8D37 IPE moduleSILC and UILC pair-terminations for connectors A, E, K, R (12-cable conﬁguration)" (page 33).

Note: In Table 5 "NT8D37 IPE moduleSILC and UILC

pair-terminations for connectors A, E, K, R (12-cable conﬁguration)" (page 33) through Table 11 "Card location form: NT8D37 IPE module (12-cable conﬁguration)" (page 44),

the cable pair designated T- T+ is the transmit pair and the pair designated R+ R- is the receive pair of the S/T interface. The cable pair designated T R is the Tx and Rx of the 2B1Q full-duplex U interface.

Identify building wires connected to the bottom of the distribution strip. Refer to the Building Cable Plan, which identiﬁes wires between distribution frames and wall outlets. The Building Cable Plan is developed according to instructions in the "Planning the Site" section in Communication Server 1000M and Meridian 1 : Large System Planning and Engineering (553-3021-120).

Plug in the terminating resistor at the appropriate location in each S/T DSL. See "Engineering Guidelines" in the ISDN Basic Rate
