MISPs

• MISPs are inserted into the CE/Network Module for options 51C and
61C, and the Network Module for options 81C. Refer to the LD 22
printout to identify modules with unused network card slots and to
Table 1 for the card slots in these modules that can house MIS Ps.

• An MISP cannot share network loop addresse s with a Superloop
Network Card in opt ions 51C, 61C, and 81C. The MISP req uires two
network loop ad dres s es and one network card slot.

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

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

• An MISP can support both BR SCs and SIL Cs or UILCs at the sa me time.
If it serves one BRSC, a MISP can also support three line cards. If it
supports two or more BRSCs, a MISP can also support two line cards.

BRSCs

• Install one BRSC per IPE module.

• With a BRS C configured, an IPE module can support a m aximum of 15
line cards. These may be up to eight UILCs combined with any other
seven peripheral cards (including SILCs), or up to 15 SILCs.

SILCs/UILCs

• SILC s, UI LC s an d BR S C s ar e in s t al l ed in to th e IP E ca r d sl ot s of th e
CE/PE Modul e and/or the IPE Module for opti on 21E. They are install ed
into the IPE Modul e for al l other system options. Refer to the LD 20
printout to identify modules with unused peripheral card slots.

553-3901-200 Standard 7.00 January 2002

• In each module, install a maximum of 15 SILCs , or ei ght UILCs
combined with an y other seven periphera l cards (includi ng 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 res triction is due to powe r supply
limitations for the module). If 8 UILCs are used, you may install any
other card which could reside in the IPE module.

• Group a ll S ILCs, UILCs , BRS Cs a nd the MI SP that support s t hem i n the
same network gr oup to avoid using junctors for dedicated connections.
The figures th at follow show typical module configurations.

Cross-connect the MDF

The MDF cross-connects NE-A25B cables conne cted to SILC and UILC
ports with bui lding wiring connected to ISDN BRI terminals.

Each SILC provide s e ight four-wire full duplex ports. These ports ar e
connected to building wiring to form DSLs. These ports are pola rity sensitive .
Signal polarity must be maintained along each loop.

Each UILC provides eight two-wire full duplex ports. These ports are
connected to twi sted pair buildi ng wiring to for m DSLs. These DSLs are not
polarity sensitive and, although it is recommended, it is not necessary to
maintain signal polarity along each loop.

Figure 7 and Figure 8 illustrate, respectively, a cross-connection of a n SILC
port and an UILC port to the building wiring.

Cross- connect SIL C and/or UILC ports to the bui l di ng w iring

1 Identify t he card type (SILC or UILC) for a connector on the MDF.

Refer to the I PE or CE/PE module card l ocation fo rm, which shows the
card type connected to each I/O panel con nector.

2 Identify t ransmit and rec eive pairs on the top of the labeled distr ibution

strip for the ca rd t ype and m odule type you are conn ecting . To id entif y
SILC or UILC ports and their pin numbers, refer to Tables 4 through
10, which follow the i ll ustrations.

Note: In Tables 4 thro ugh 10, 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.

3 Identify build ing wires connect ed t o the bo ttom of th e dist ribut ion st rip.

Refer to the Building Cable Plan, which identifies wires between
distribution frames and wall outl ets.

4 Plug in the termi nating resistor (Part Number A0378866) at the

appropriat e location in each S/T DSL. See “Engineeri ng Guidelines” in
the ISDN Basi c Rate Interfa ce: Product Descr iption (553-3901- 100) for
engineering rules and locat ions of terminating resistors.

Connect the ISDN BRI terminals to the DSL

ISDN BRI terminals are connected to DSLs using modular cables up to 10
meters (33 feet) long, with RJ-45 plugs on each end. One end of the cable
plugs int o the te rminal and the other end plugs into the wall outlet.

Note: All ISDN BRI terminals should comply with CCITT , ANSI,
ETSI NET-3, INS NET-64, National ISDN, 1TR6, Numeris VN2, and
D70 standards for terminals, and be compatible with Meridian 1. For a
list of co m p at ib le ter m i na l s , re f er to th e ISDN Ba si c Ra te Int erf a ce :
Product Description (553-3901-100) .

Figure 9 illustrates a terminal connection to the S/T interface; Figure 10
illust rates a network termination (NT1) connection to the U interface.

1 Plug one end of the modular cable into the ISDN BRI interface

connector on the t erminal , and th e oth er end of the mod ular ca ble int o
the wall outle t.

2 For an SILC S/T interface terminal with an optional auxiliary power

source, plug the power source into the wall outlet, then plug the cable
into the power source's RJ-45 jack. This power source must supply
power only to the local ISDN BRI terminal, not back into th e DSL
through the RJ-45 wal l outlet. The power adapter i s supplied with the
terminal.

3 Program the terminal parameters, such as the SPID and TEI, as

required by the type of terminal. For detailed information pertaining to
this procedure, refer to the section “Initialize ISDN BRI terminals”,
found in ISDN Basic R ate Inte rface: A d m inistration (553-3901-300).

4 Repeat steps 1 and 3 for each terminal to be connect ed.

—————————— End of Proce d u re ——————————

Connect the terminating resistors

DSLs requir e that a terminating resistor

(Part Number A0378866) be

connected at the end of each loop. See ISDN Basic Rate Interface: Product
Description (553-3901-100) , for engineering r u les and locations of

terminati ng res istors. The end of the S/T inte rface loop has a RJ-45 jack to
plug in the tel ephone cable. Plug the terminating resistor into the RJ-45 and
then plug t he tele phone cable in to the t erminating r esisto r. Note tha t for every
port there is one loop with only one te rmi nating resistor per loop. Each loop
may have up to eight telephones.

Install ISDN BRI hardware for trunk applications

The following lists the procedures for install ISDN BRI hardware for ISDN
BRI trunk applications. Meridian 1 must already be installed and operating
according to the instru ctions in System Insta llation Procedur es
(553-3001-210) before performing these procedures.

For a successful ins tallation, perf orm these procedures in the order listed
below:

1 Select the card sl ots where the ISDN BRI cards will be loc ated
2 Install the MISP
3 Install clock referencing on th e SILC
4 Install the SILC and/or UI LC
5 Connect Meridian 1 to the MDF
6 Cross-connect the MDF (in Termina l Equipment mode)

Note: The Meridian 1, in Tie trunk or CO connectivity, requires a
different wiri ng configurat ion than for a line app lication; th e transmit and
receive pai rs should be reversed, as illus trated in Figure 12.

Select the card slots

Follow the same proc edures as describe d earlier for line applications (refer to
“Se le ct th e ca r d sl ot s ” on page 15).

Remove the module cover for card installation

Follow the same proc edures as describe d earlier for line applications (refer to
“Remove the module cover for card installation” on page 19).

Install the MISP

Follow the same proc edures as describe d earlier for line applications (refer to
“In st all the MI S P” on page 20).

Install the clock reference on the SILC

The DSL#0 and DSL#1 on an SILC card can be configured as the reference
clock sourc e, with DSL#0 being assig ned for the prim ary clock refere nce and
DSL#1 being assigne d for the secondary clock refere nce .

553-3901-200 Standard 7.00 January 2002

Install ISDN BRI hardware Page 39 of 46

The loop number and location of the primary and secondary clock s ource is
configure d in the Digit al Data B lock overl ay 73. Refer to the ISD N Basi c Rate
Interface : Admi nistration (553-3901-300).

The following proc edure shoul d be followe d to pro vide clock re ferenc ing on
the SILC.

Note: For procedures on how to install the QPC775/QPC471 Clock
Controlle r on the vari ous Meri dian 1 syst ems, pl ease refer to ISDN PRI:
Installation (553-2901-201).

1 Maintai n the same polarity on each tran sm it and receive. Rewire the

selecte d Tx and Rx pairs (applica ble to DSL0 and DSL1), to exchange
the Tx and Rx pair position. Thi s rewiring is done at the Main
Distribut ion Frame (MDF).

2 Remove the phantom power jumpers (two jumpe rs per DSL) from the

pin headers .

3 Place the SILC in the selected IPE slot.
4 Configure the sel ected DSL as TE mode (in overlay 27).
5 Enable the clock in overlay 60, to output the clock references to the

IPE back plane pins.

6 Configure the Cl ock Controller card to accept ISDN BRI clock

reference.

7 Check the appropriate messages from the Clock Controller to ensure

that it i s synchr oni zed to the pro per clock r efere nce ( this is done using
overlay 60).

8 Connect the ISDN BRI clock refer ence cab les to the Clock Control ler,

using the procedures which follow.

1 Search for avail able D-sub 9 connector slots on the I/O panels of the

selecte d IPE and CE I/O modules (if the I/O panel is equipp ed with
D-sub 9 connector slots). If none is available, look for an empty slot
used for 25 pair wire conn ectors ( the cable s contain two adapte r plates
to convert an 25 wire slot to two D-sub 9 connector slots).

2 Connect the cables as shown in Figure 11; if choosing IPE slots 0, 4,

Clock recovery

The SILC is configured in the slave-sla ve mo de whe n act ing as a trunk
interfa ce. This is se t up through the Maintenanc e Signaling Channel (MSC) .
The microcontroller configures the S/T chips on the SILC as appropriate.

The SILC may re cover the n etwork clock from the receiv ed data str eam using
on-chip phase lock loops. The clock frequency which is recovered is 2.56
MHz. The jitte r and wan der conform to CCITT recommendations.

Page 42 of 46 Install IS D N BR I ha r dware

All of the S /T c hips o n th e SI LC c ould be co nfigu red as Term inal Equ ipmen t
Slaves (TES), but onl y the clocks re covered from DSL0 and DSL1 are routed
to the back plane connector pins. Thes e cl ocks are provided as differ ential
pairs on back pla ne pins, as follows: in

Secondary 75 +Ref 0B - Ref 0B
Secondary 76 +Ref 1B - Ref 1A

Automatic c lock recovery is done upon the exp iration of the free run guard
timer. Tracking is restored to the primary reference clock, if defined. If the
primary refere nce clock is disable d, tracking is restore d to the secondary
reference clock, if defined.

Install the SILC and the UILC

Follow the same proc edures as describe d earlier for line applications (refer to
“Install t he BRSC, SILC and UILC” on page 21).

Connect Meridian 1 to the Main Distribution Frame (MDF)

Follow the same proc edures as describe d earlier for line applications (refer to
“Connect Meridian 1 modul es to the MDF” on pag e 2 4) .

Cross-connect the Main Distribution Frame (MDF)

The Meridian 1, in Tie trunk or CO connectivity, requires a different wiring
configura tion than for a line applica tion; the transmit and receive pairs shoul d
be reversed, as illustrated in Figure12.
