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:
z WireSpan 600 – fractional E1 access unit, for applications
that integer multiples of 64kbps range from 1 through 32,
corresponding to a maximum of 2048 kbps.
z WireSpan 610 – Unframed only, for applications that fix
2048M bps data rate.

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:
z DCE – 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.

Description
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:
z Internal clock oscillator, having an accuracy of ±30 ppm
z The recovered receive clock signal. The maximum track
range is ±130 ppm
z Lock 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.
z Internal 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.

z E1 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.

1. External
problem
2. Problem at
local end
3. Problem at
remote end
Activate the local loopback. Check
that the local WireSpan 600 / 610
SYN indicator is On.
If indicator off, turn the local
Wirespan 600 / 610 on with the
local loopback activated.
Check that the BPV and AIS alarm
indicator turns off. If not, replace
the WireSpan 600 / 610
Troubleshoot the E1 link between
the local and the remote WireSpan
600 / 610
Check that the user’s equipment is
powered, and its control signal
lines are asserted. Perform self-test
on the equipment
check that the local user;s
equipment receives its own
transmission. If not, replace the
cable connecting it to the Wirespan
600 / 610
Activate the digital loopback, and
check remote E1 equipment
receives its own transmission. If
not, troubleshoot the remote
Wirespan 600 /610 and thee E1
link
