Overview
The HP E1663A SONET/SDH Electrical Interface is a member of the HP Broad-
band Series of modular VXI-based B-ISDN test instruments. The HP E1663A acts
as the interface between the HP Broadband Series Test System and the System
Under Test, transmitting and receiving 155.52 Mb/s or 52 Mb/s SONET/SDH trans-
mission signals.
The HP E1663A is used in conjunction with the HP E1697A 155 Mb/s Optical Line
Interface or the HP E1617A 52 Mb/s Optical Line Interface, and communication
between the modules is by SMA to SMB Radio Frequency (RF) adaptor cables.
See “Connecting to an Optical Line Interface”, page 2-4.
The Electrical Interface provides signal encoding at the appropriate levels and
format required by the System Under Test. Data is transmitted in the binary CMI
(Coded Mark Inversion) format at 155.52 Mb/s or 52 Mb/s.
The data stream received from the System Under Test is CMI at 155.52 Mb/s or 52
Mb/s. The clock is recovered from the incoming data, and automatic compensation
for cable loss and signal loss is provided.
Module Identification
An identification label is attached to the Electrical Interface clamshell enclosure.
The serial number is in the form “0000U00000'”. It is in two parts: the first four
digits and the letter are the serial prefix, and the last five digits are the suffix. The
prefix is the same for all identical modules and changes only when a change is
made to the module. The suffix, however, is assigned sequentially and is unique to
each module. The contents of this manual apply to instruments with the serial
prefix(es) listed under SERIAL NUMBERS on the title page.

Functional Features
The Electrical Interface transmits and receives data at the SONET/SDH data rate
of 155.52 Mb/s. Communication with the 155 Mb/s Optical Line Interface and the
System Under Test is by RF cables fixed to connectors on the front panel.
Figure 1.1 shows a typical system configuration. The System Under Test can be a
complete transmission system, or individual system components. See “Connecting
to an Optical Line Interface”, page 2-4 and “Connecting to the System Under
Test”, page 2-5 for further details.
Figure 1.1 Typical Configuration
See the HP E1697A 155 Mb/s Optical Line Interface User’s Guide (HP p/n E1697-
90002) for guidance when configuring the 155 Mb/s Optical Line Interface.
Transmitter
The HP E1697A supplies binary NRZ (nonreturn to zero) formatted data signals
and associated clock signals to the input of the Electrical Interface. The Electrical
Interface then applies CMI encoding to the signal before passing it to the System
Under Test.

Introduction
Functional Features
Receiver
The receiver side of the Electrical Interface provides signal amplification, √ƒ
equalization, clock recovery, and CMI decoding at 155.52 Mb/s. The signal is then
passed to the HP E1697A for processing.
Monitor Point Access
The signal amplification circuitry provides a fixed 20 dB gain to recover typical
monitor point signals. The signal can be switched through the monitor amplifier as
required.
Equalization
The equalization circuitry automatically compensates for signal degradation
caused by cable loss in the network, and applies the √ƒ law for cables.
Clock Recovery and Decoding
The receiver clock is recovered from the data stream for the subsequent decoding
circuitry. Decoding produces data signals in binary NRZ format, and both the
clock and regenerated data signals are passed to the HP E1697A for processing.

ESD Precautions
The Electrical Interface contains components sensitive to electrostatic discharge.
To prevent component damage, carefully follow the handling precautions pre-
sented below.
The smallest static voltage most people can feel is about 3500 volts. It takes less
than one tenth of that (about 300 volts) to destroy or severely damage static sen-
sitive circuits. Often, static damage does not immediately cause a malfunction but
significantly reduces the component's life. Adhering to the following precautions
will reduce the risk of static discharge damage.
• Keep the module in its conductive plastic bag when not installed in the VXI
mainframe. Save the bag for future storage of the module.
• Before handling the module, select a work area where potential static sources
are minimized. Avoid working in carpeted areas and non-conductive chairs.
Keep body movement to a minimum. Hewlett-Packard recommends that you
use a controlled static workstation.
• Handle the module by its front panel. Avoid touching any components or edge
connectors. When you are ready to configure the module, remove it from its
protective bag and lay it on top of the bag while keeping your free hand in
contact with the bag. While configuring the module, keep one hand in contact
with the bag. This technique maintains your body and the module at the same
static potential.
• When you install the module, keep one hand in contact with the protective bag
as you pick up the module with your other hand. Then, before installing the
module, make contact with the metal surface of the VXI mainframe with your
free hand to bring you, the module, and the mainframe to the same static
potential. This also applies whenever you connect/disconnect cables on
the front panel.
The connectors on the front panel remain susceptible to ESD damage while the
module is installed in the VXI mainframe, as indicated by the label:

Service
The performance of the Electrical Interface should be verified annually to ensure
that it is operating within the specifications. To do this, see the HP 75000
Series 90 HP E1663A SONET/SDH Electrical Interface User’s Manual (HP p/n
E1663-90001).
If it is necessary to return the Electrical Interface to Hewlett-Packard for service,
ensure the following information is sent with the module:
• Description of the problem (include error messages or specific performance
data related to the problem).
• Whether the problem is constant or intermittent.
• Name and phone number of technical contact person.
• Return address.
• Model and option number of returned module.
• Full serial number of returned module.
Exchange Program
This program allows you to obtain a fully tested and guaranteed restored-
exchange module at a reduced price. (The reduced price is contingent upon
return of the defective module to Hewlett-Packard.)
The procedure for replacing a faulty Electrical Interface using the assembly-
exchange program is as follows:
1 Order the replacement module (HP p/n E1663-69101) through your nearest
HP Sales and Service Office.
Do NOT return the faulty module to Hewlett-Packard until you receive the
restored-exchange module.
2 Complete the Exchange Failure Report which accompanied the restored-
exchange module.
3 Return the faulty module and the Exchange Failure Report to Hewlett-Pack-
ard; re-use the special (exchange assembly) carton.
Remove all accessories attached to the Electrical Interface before it enters the
assembly-exchange program. Accessories are NOT exchangeable.

Storage and Shipment
The Electrical Interface may be stored or shipped in environments within the fol-
lowing limits:
The module should also be protected from temperature extremes which may
cause condensation within the clamshell enclosure.
Packaging Requirements
To prevent damage to the module during transit, original shipping or equivalent
materials should be used to package the module. Containers and material identical
to those used in the factory packaging are available through Hewlett-Packard
offices. If the original or equivalent shipping material cannot be obtained, instruc-
tions for repackaging with commercially available materials are as follows:
1 Wrap the module in anti-static plastic to reduce the possibility of damage
caused by ESD.
2 Use a double walled, corrugated cardboard carton of 90 kg (200 lb) test
strength. The carton must be large enough to allow 5 to 8 cm (2 to 3 in) on all
sides of the module for packing material, and strong enough to accommodate
the weight of the module.
3 Surround the module with 5 to 8 cm (2 to 3 in) of packing material to protect
the module and prevent it from moving in the carton.
NEVER use styrene pellets as packaging material. They do not adequately cushion
the module, or prevent the module from moving in the carton. They also cause
damage by generating static electricity.
If packing foam is not available, the best alternative is S.D.-240 Air Cap from
Sealed Air Corporation (Commerce, California 90001). Air Cap looks like a plastic
sheet with air bubbles. Wrap the module with several layers of pink (anti-static)
Air Cap to protect the module, and prevent the module from moving within the
carton.
Temperature : −40°C to +75°C.
Humidity : 50% to 95% RH from 25°C to 40°C.
Altitude : Up to 4600 m (15,000 ft).
