Select the card slots  
To install ISDN BRI cards, perform the following steps:  
1
Identify all the slots that can contain them. First identify the modules  
with unused network and peripheral card slots and then remove the  
covers from the identified modules. To identify the modules, use the  
following Print Programs. Table 1 lists the modules that can house  
ISDN BRI cards.  
LD 22 to print the system configuration and identify unused  
network card slots to install MISPs  
LD 20 to list unused IPE card slots to install SILCs, UILCs and  
BRSCs

Locate the card slots in the Meridian 1 modules which can 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.  
The following rules apply when selecting the card slots:  
ISDN Basic Rate Interface Installation  
 
   
Page 16 of 46  
Install ISDN BRI hardware  
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 MISPs.  
An MISP cannot share network loop addresses with a Superloop  
Network Card in options 51C, 61C, and 81C. The MISP requires two  
network loop addresses 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 BRSCs and SILCs or UILCs at the same 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 BRSC configured, an IPE module can support a maximum 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  
SILCs, UILCs and BRSCs are installed into the IPE card slots of the  
CE/PE Module and/or the IPE Module for option 21E. They are installed  
into the IPE Module for all 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  
 
Install ISDN BRI hardware Page 17 of 46  
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 8 UILCs are used, you may install any  
other card which could reside in the IPE module.  
Group all SILCs, UILCs, BRSCs and the MISP that supports them in the  
same network group to avoid using junctors for dedicated connections.  
The figures that follow show typical module configurations.

Note 1: For the SILC port designations shown in this table, substitute Tx- Tx+ Rx+ Rx- for every  
occurrence of T- T+ R+ R-.  
Note 2: The cable pair designated Tx- Tx+ is the transmit pair. The pair designated Rx+ Rx- is the  
receive pair. An SILC port supplies 2 watts of power at -48 V (-40 V for international), simplexed over the  
transmit and receive pairs, where the transmit pair is negative with respect to the receive pair.

Note: The cable pair designated TR is a 2B1Q full duplex U interface.  
Cross-connect the MDF  
The MDF cross-connects NE-A25B cables connected to SILC and UILC  
ports with building wiring connected to ISDN BRI terminals.  
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 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 an SILC  
port and an UILC port to the building wiring.

Install ISDN BRI hardware Page 29 of 46  
Cross-connect SILC and/or UILC ports to the building wiring  
1
Identify the card type (SILC or UILC) for a connector on the MDF.  
Refer to the IPE or CE/PE module card location form, which shows the  
card type connected to each I/O panel connector.  
2
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 Tables 4 through  
10, which follow the illustrations.  
Note: In Tables 4 through 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
4
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.  
Plug in the terminating resistor (Part Number A0378866) at the  
appropriate location in each S/T DSL. See Engineering Guidelinesin  
the ISDN Basic Rate Interface: Product Description (553-3901-100) for  
engineering rules and locations 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 into the terminal 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 compatible terminals, refer to the ISDN Basic Rate Interface:  
Product Description (553-3901-100).  
Figure 9 illustrates a terminal connection to the S/T interface; Figure 10  
illustrates 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 terminal, and the other end of the modular cable into  
the wall outlet.  
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 the DSL  
through the RJ-45 wall outlet. The power adapter is supplied with the  
terminal.  
3
4
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 Rate Interface: Administration (553-3901-300).  
Repeat steps 1 and 3 for each terminal to be connected.  
—————————— End of Procedure ——————————  
Connect the terminating resistors  
DSLs require 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 rules and locations of  
terminating resistors. The end of the S/T interface loop has a RJ-45 jack to  
plug in the telephone cable. Plug the terminating resistor into the RJ-45 and  
then plug the telephone cable into the terminating resistor. Note that for every  
port there is one loop with only one terminating resistor per loop. Each loop  
may have up to eight telephones.

Search for available D-sub 9 connector slots on the I/O panels of the  
selected IPE and CE I/O modules (if the I/O panel is equipped with  
D-sub 9 connector slots). If none is available, look for an empty slot  
used for 25 pair wire connectors (the cables contain two adapter plates  
to convert an 25 wire slot to two D-sub 9 connector slots).  
Connect the cables as shown in Figure 11; if choosing IPE slots 0, 4,  
8, or 12 the transmit and receive cable installed on pins 72 - 79 should  
be removed and secured to a proper place.

Clock recovery  
The SILC is configured in the slave-slave mode when acting as a trunk  
interface. This is set up through the Maintenance Signaling Channel (MSC).  
The microcontroller configures the S/T chips on the SILC as appropriate.  
The SILC may recover the network clock from the received data stream using  
on-chip phase lock loops. The clock frequency which is recovered is 2.56  
MHz. The jitter and wander conform to CCITT recommendations.

Page 42 of 46  
Install ISDN BRI hardware  
All of the S/T chips on the SILC could be configured as Terminal Equipment  
Slaves (TES), but only the clocks recovered from DSL0 and DSL1 are routed  
to the back plane connector pins. These clocks are provided as differential  
pairs on back plane pins, as follows: in
