CHAPTER 1
Introduction
1.1 Overview
WireSpan 600 is a cost-effective, single-port fractional E1 access unit.
The fractional E1 service makes unused time slots on long-range E1
trunks available for other users.
WireSpan 600 provides a synchronous data channel that supports
user-selectable transmission rates. The available data rates are integer
multiples of 64 kbps; the multiples range is 1 through 32, corresponding to
a maximum of 2048 kbps. The user’s payload data is packed in the
corresponding number of time slot of an E1 (CEPT 2.048 Mbps) data
stream, for transmission over public or private E1 networks.
Versions
WireSpan 600 is available on two models:
zWireSpan 600 – fractional E1 access unit, for applications
that integer multiples of 64kbps range from 1 through 32,
corresponding to a maximum of 2048 kbps.
zWireSpan 610 – Unframed only, for applications that fix
2048M bps data rate.

Connectors
The power and interface connectors are located on the lateral panel of
WireSpan 600 / 610. A description of the lateral panel can be found in
interfaces and connectors.
1.3 Functional Description
WireSpan 600 / 610 has a synchronous user’s data port interface. The
electrical interface is user-selectable. The user’s data port is terminated in
a 50-pin SCSI-type female connector. ITU-T Rec. V.35, EIA RS-530,
RS-449 and X.21 interfaces are supported by means of adapter cables.

The user’s data port has two timing modes:
zDCE – WireSpan 600 provides transmit and receive clocks for
the user’s equipment connected to the data port. And accepts
XTC clock from the equipment. Figure 1-3 shows the flow of
timing signals through the user’s data port in the DCE mode.

E1 Interface Characteristics
The WireSpan 600 E1 link interface meets the requirements of ITU-T
Rec. G.703, G.704, G.706, G .823.
The E1 link has two line interfaces: a 120-ohm balanced line interface
terminated in a RJ-48 eight-pin female connector, and a 75-ohm
unbalanced interface terminated in two BNC female coaxial connectors.
Line coding is HDB-3 or AMI. The nominal balanced interface transmit
level is ±3V, and the unbalanced interface transmit level is ±2.37V. Jitter
performance complies with the requirements of ITU-T Rec. G.823.
1-4

The E1 link interface supports PCM 31 frames (time slot 16 available
for user’s data), and PCM 30 frames (time slot 16 not available for user’s
data). WireSpan 600 also supports the CRC-4 option specified in ITU-T
Rec. G.704. The framing mode and the use of the CRC-4 option are
independently selectable by the user.
In addition, WireSpan 600 can also operate in the unframed mode. In
this mode, WireSpan 600 / 610 operates as an interface converter, enabling
the transfer of unstructured 2.048 Mbps data streams (or data streams with
proprietary framing generated by equipment with ITU-T Rec. V.35, EIA
RS-530, EIA RS-449), and X.21 interfaces via the E1 network.
Note The WireSpan 610 always operates in unframed mode.
The user can select the number of main link time slots used to carry
the payload data.
The timing of the receive path of the Wirespan 600 / 610 E1 link
interface is always locked to the clock signal recovered from the received
line signal. The timing of transmit path can be locked to one of the
following three sources:
zInternal clock oscillator, having an accuracy of ±30 ppm
zThe recovered receive clock signal. The maximum track
range is ±130 ppm
zLock data port clock signal. The maximum track range is
±100 ppm
Control of WireSpan 600 Operation
WireSpan 600 is designed for fully automatic, unattended operation.
Its configuration is determined by keypads and LCD-menu. Top panel
LED indicators and LCD display show the operating status of WireSpan
600. Various indicators display the E1 link status and user’s data port
status, and alert when an alarm condition (major or minor) or test loops are
present in the system.
WireSpan 600 / 610 has comprehensive diagnostic capabilities that
1-5

include LL and DL loopbacks, controlled by top panel keypads and
LCD-menu. Maintenance is further enhanced by a power-up self-test.
Selection of System Timing Mode
This section explains the interaction between the user’s port timing
mode, and the E1 link transmit timing mode.
zInternal timing mode: The WireSpan 600 / 610 E1 link
transmit signal is derived from the internal clock oscillator.
This timing mode used is necessary in point-to-point
application over leased lines, e.g., short-range applications,
where one WireSpan 600 / 610 must provide the timing
reference for the link. In this case, one WireSpan 600 / 610
must use the internal oscillator, and other must operate on the
recovered clock signal. Note that when the internal oscillator
is used, the DCE or DTE timing mode should be selected to
synchronize the user data rate to the E1 link timing.
Figure 1-5 shows a typical system application using the internal
timing mode on conjunction with DCE timing.

zE1 timing mode: With E1 timing, the WireSpan 600 /
610 link transmit signal is locked to the recovered E1
receive clock. This is usually the timing mode selected
for network operation, as shown in Figure 1-6. In the
application illustrated in Figure 1-6, the master clock of
the network determines the timing of the two WireSpan
600 / 610 units. In case the E1 receive signal is lost,
WireSpan 600 / 610 automatically switches to the
internal oscillator.

the timing mode selected for E1-Mux. application.

2-2

printed circuit board, the procedure is the same.
Warning : ELECTRICAL SHOCK HAZARD: Access to the
inside of the unit is permitted only to qualified and
authorized service personnel.
Any adjustment, maintenance, and repair of the opened
instrument under voltage should be avoided as much as
possible and, when inevitable, should be carried out only
by a skilled technician who is aware of the hazard
involved. Capacitors inside the instrument may still be
charged even after the instrument has been disconnected
from its source of supply.
Caution WireSpan 600 / 610 contains components sensitive to
electrostatic discharge (ESD). To prevent ESD damage,
avoid touching internal components and before moving
jumpers, touch the WireSpan 600 / 610 frame.
E1 Link Connections
WireSpan 600 / 610 E1 link has an RJ-48C eight-pin connector for the
balanced interface, and two BNC connectors for the unbalanced interface.
Appendix A, E1 Balanced Port Connector provides the pin allocation for
the RJ-48C connector.
Connector the E1 link cables to the connector(s) corresponding to the
interface in use.
Warning Do not connect to both the balanced and unbalanced
connectors!
zWhen using the balanced interface, connect to the
