The customer should be aware that compliance with the above conditions may not
prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian
maintenance facility designated by the supplier. Any repairs or alternations made by
the user to this equipment, or equipment malfunctions, may give the
telecommunications company cause to request the user to disconnect the
equipment.
User should ensure for their own protection that the electrical ground connections
of the power utility, telephone lines and internal metallic water pipe system, if
present, are connected together. This precaution may be particularly important in
rural areas.

1. PRODUCT DESCRIPTION
1.1 Overview
The Loop-V 4200-9 is a versatile 9-port device. Depending on the plug-in cards selected, this unit can be
configured (a) as a CSU/DSU with drop and insert and voice capabilities, (b) as a 4 E1 to 5 T1 converter or
fractions of them, (c) as a digital cross-connect system (DACS), (d) as sets of ICSU combined in one box,
and (e) as a channel bank. As a CSU/DSU, data from the V.35 or X.21 port can occupy any fraction of an
E1 or T1 port. As an E1 to T1 converter, A to µlaw and signaling conversions are correctly handled. For
both E1 and T1 ports, continuous error checking, performance polling, and in-service diagnostics are
provided. In any of the above combinations, full time slot interchange (TSI) among the ports are possible,
making the Loop-V 4200-9 a small DACS (digital access cross-connect system). The ports can further be
used in pairs as ICSUs (intelligent CSU) at lower cost and smaller space than individual ICSUs. Lastly, the
Loop-V 4200 can be configured as a channel bank.
The Loop-V 4200-9 supports local control and diagnostics by using a 2-line by 40-character LCD display and
keypads on the front panel, or by using a VT-100 terminal connected to the console port. The Loop-V 4200-9
also supports Ethernet, Telnet, and SNMP, so it can be controlled and diagnosed from remote locations. The
Loop-V 4200-9 also supports inband Management, where management data is carried the same way as user
data, traversing national networks.
In addition to the LCD display, 12 multicolor LEDs provide status indication for power, test condition, alarm,
and each of the 9 ports. Internal firmware is stored in flash memory so that future software upgrades can be
downloaded.
1.2 Physical Description
Loop-V 4200 MuxMaster is a compact box that can be either rack mounted taking up 1U of rack height or
placed on desktop. Depending on the power plug-in card used, power can be either AC, DC, or dual DC
module with dual DC feed.

1.3 Applications
Because of the variety of plug-in cards available, the applications for Loop-V 4200 MuxMaster are numerous.
Only a few representative ones will be illustrated here. To the extent ports are available, combinations of
illustrated applications are possible.
Important Note on Clock Source: Since the entire system operates on a single clock source, one of the input
signal can serve as the master clock source. Each of the remaining input is presumed to synchronize to this
master clock source. To the extent that the clock of any incoming line can drift with respect to the system
clock, slips, or controlled slips, may occur.
1.3.1 As an ICSU
Figure 1- 2 As an ICSU
In this application, two slots are used in combination to provide the intelligent channel service unit (ICSU)
function. This is used to terminate E1 or T1 lines at the customer site. Performance monitoring and
maintenance functions, such as local and remote loop backs, are available. By using 4 slot-pairs, 4
independent ICSUs can be realized (see note on Clock Source above).

Figure 1- 3 As a one-to-one E1/T1 Converter
In this application, two slots are used in combination to provide one-to-one E1 to T1 conversion function.
Because of the lower bit rate of the T1 line, only 24 time slots of the E1 line can be utilized in this
interconnection. User can assign any 24 of E1 time slots to any of the 24 T1 time-slots. For digitized voice,
A-law to µ-law conversion will be performed. For CAS (channel associated signaling), the signaling bits will
be placed in their proper places in the respective E1 and T1 formats. Performance monitoring and
maintenance functions, such as local and remote loop backs, are available. By using 4 slot-pairs, 4
independent one-to-one E1 to T1 converters can be realized (see note on Clock Source above).
In a related application, time slots left over on the E1 side can be filled with data from a DTE plug-in card.

1.3.3 As a One-to-Two E1 to T1 Converter
Figure 1- 5 As a One-to-Two E1/T1 Converter
In this application, three slots are used in combination to provide one-to-two E1 to T1 conversion function.
Because of the combined bit rate of two T1 lines is higher than one E1, all 31 time slots of the E1 line can be
assigned. User can assign each of 31 E1 time slots to any of the 48 time-slots available in 2 T1s, with time
slots left over in the T1s. For digitized voice, A-law to µ-law conversion will be performed. For CAS (channel
associated signaling), only 30 time slots can be assigned with the signaling bits placed in their proper places
in the respective E1 and T1 formats. Performance monitoring and maintenance functions, such as local and
remote loop backs, are available. By using all eight available slots, 2 independent one-to-two E1 to T1
converters can be realized along with a one-to-one converter (see Clock Source note above).
In a related application, similar to Figure 1-4, time slots left over in one or both T1s can be filled with data
from a DTE plug-in card.

Figure 1- 6 As a Four-to-Five E1/T1 Converter
In this application, an optional 9-slot version of the Loop-V 4200 MuxMaster is used to provide four-to-five E1
to T1 conversion function. Each E1 is assumed to use only 30 time slots with time slot 16 reserved for
signaling. Because the total time slots for four E1 lines and for five T1 lines are both 120, both bundles can
be fully occupied for traffic. User can assign any of 30 time slots from any of four E1 lines to any of the 24
time-slots of any of five T1s. For digitized voice, A-law to µ-law conversion will be performed. For CAS
(channel associated signaling), the signaling bits will be transferred to their proper places in the respective
E1 and T1 formats. Performance monitoring and maintenance functions, such as local and remote loop
backs, are available. This application provides users with utilization of both E1 and T1 lines.
