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.

•
•
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
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.

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
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.

Cross-connect SILC and/or UILC ports to the building wiring
1
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.

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 Guidelines” in
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
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

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 instructions in System Installation Procedures
(553-3001-210) before performing these procedures.
For a successful installation, perform these procedures in the order listed
below:
1
2
3
4
5
6
Select the card slots where the ISDN BRI cards will be located
Install the MISP
Install clock referencing on the SILC
Install the SILC and/or UILC
Connect Meridian 1 to the MDF
Cross-connect the MDF (in Terminal Equipment mode)
Note: The Meridian 1, in Tie trunk or CO connectivity, requires a
different wiring configuration than for a line application; the transmit and
receive pairs should be reversed, as illustrated in Figure 12.
Select the card slots
Follow the same procedures as described earlier for line applications (refer to
“Select the card slots” on page 15).
Remove the module cover for card installation
Follow the same procedures as described earlier for line applications (refer to
“Remove the module cover for card installation” on page 19).

Maintain the same polarity on each transmit and receive. Rewire the
selected Tx and Rx pairs (applicable to DSL0 and DSL1), to exchange
the Tx and Rx pair position. This rewiring is done at the Main
Distribution Frame (MDF).
Remove the phantom power jumpers (two jumpers per DSL) from the
pin headers.
3

5
Place the SILC in the selected IPE slot.
Configure the selected DSL as TE mode (in overlay 27).
Enable the clock in overlay 60, to output the clock references to the
IPE back plane pins.

7
Configure the Clock Controller card to accept ISDN BRI clock
reference.
Check the appropriate messages from the Clock Controller to ensure
that it is synchronized to the proper clock reference (this is done using
overlay 60).

Connect clock reference cables
The following procedure should be followed to connect the ISDN BRI clock
reference cables to the Clock Controller. There are three different cables that
route clock signals from the IPE back plane to the Clock Controller face plate
(as shown in Figure 11). These are shown in Table 7.:

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.

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
