Examples of Card Configuration

The performance configuration is additive from the base configuration. For
example, to set up the performance configuration for four AP cards and two TP
cards, add an IFP card in slot 7 to the base configuration. The resulting
configuration is:

AP1, AP2, AP3, AP4, TP11, TP12, IFP6, IFP7, IFP8, SSP9
The redundant configuration is additive from the performance configuration. For

example, to set up the redundant configuration for four AP cards and two TP
cards, add an AP card in slot 5 and an SSP card in slot 10. The resulting
configuration is:

Versalar 15000 Hardware Description

Each AP card services the access interface card corresponding to the slot number
of the installed AP card. For example, the AP card installed in processor card slot
2 services the access interface card installed in interface card slot 2.

The function of a physical interface card in the rear of the chassis must

Note:

match the function of the AP card in the corresponding slot in the front of the
chassis, for example, ATM to ATM or T3 to T3.

An AP card installed in slo t 5 ca n provide failov er se rvi ce to the AP cards in slots
1 to 4. For more informat ion about redundancy, see “Access Redundancy Module
Interface Card” on page 1-26

.

The Versalar 15000 supports four types of AP cards:

• The M13 channelized acc ess processor (CAP) card is use d f or subrate T1 and
T1 applications.

• The DS3 CAP card provides high-speed access over DS3 lines.

• The hybrid M13 and clear-channel DS3 CAP card provides both T1 and
high-speed access.

308684-B Rev 00

• The ATM (asynchronous transfer mode) a cce ss p roc essor card provides ATM
access via DS3 or OC-3 lines.

Each AP card consists of a printed circuit board, an EMI card shield, a bezel with
status LEDs, and 2 captive screws to secure the card in place (Figure 1-2

).

AP Card Labels

The AP cards are differentiated from each other by their labels only. Otherwise,
the cards appear the same.

Trunk ATM Interface Cards

The Versalar 15000 trunk interface cards occupy chassis slots 11 and 12 and
support network interfaces for TP cards. This section contains information about
the following cards:

• ATM OC-12c/STM-4c single-mode and multimode trunk interface cards

• Quad OC-3 ATM trunk interface card

Single-Mode and Multimode Interfaces

The single-mode fiber (SMF) and multimode fiber (MMF) interfaces operate with
a wide variety of ATM switches and are compliant with Bellcore standards. You
can view modes as bundles of light entering the fiber at a particular angle.
Single-mode fiber allows only one mode of light to propagate through the fiber;
multimode fiber allows multiple modes of light to propagate.

Depending on the entry angles, multiple modes of light propagating through the
fiber travel different distances, thus causing them to arrive at their destination at
different times. This phenomenon is called modal dispersion, and it results in
single-mode fiber being capable of higher bandwidth and greater cable run
distances than multimode fiber. For more information about transmission
distances for single-mode and multimode fiber, see “OC-12c/STM-4c ATM
Interface Card Specifications” on page A-6.

1-36

OC-12c/STM-4c ATM Interface Cards

The ATM OC-12c/STM-4c single-mode and multimode trunk interface cards
provide an ATM OC-12c/STM-4c link-level interface. The Versalar 15000
supports one or two OC-12c/STM-4c single-mode cards, one or two
OC-12c/STM-4c multimode cards, or one single-mode and one multimode card.
You can differentiate multimode cards from single-mode cards by their labels, as
shown in Figure 1-12

, which shows a multimode card.
