1.2 Overview
The TeleLite Ethernet cards are modems with unmanaged switch interface card providing copper
(10 Base-T and/or 100 Base-TX) to optical media conversion, combining four Ethernet ports to a
single fiber port with an unmanaged four-port switch.
Several Ethernet provisioning configurations are possible with these card sets, each requiring two
cards with one at either end of the fiber span for conversion back to copper. In each configuration,
a CAT 5 Ethernet cable is required to interface with the RJ receptacles on the faceplate of the
TeleLite Ethernet cards. Power and Switch settings are common to all versions above. As such,
the model numbers herein are referred to with the suffix “xxx” rather than MST, SSC, or SXC.

1.3 General Technical Notes
1.3.1 POE
Can be powered locally (local power provided by the backplane of the TeleLite shelf)
Can be powered by -48Vdc in the appropriate polarity from the Ethernet Network Edge
Device via the first (top) Ethernet port as per POE specifications (in the appropriate
polarity). Its interface supports the two standard modes of powering using
superimposed 48 Vdc on the data pair or using the spare pin on the RJ45 in any
polarity
Has DIP switches to set:
Master/Slave
Types 1 or 2
MDIX enabling or disabling (Disabled is default). Check modems if they are
MDIX enabled. If they are not, this feature should be enabled to avoid cross-
over issues.
PSE enabling or disabling (Used only on 720920xxx. On 720930xxx, this switch
(#4) is always to be set to “Disabled”)
1.3.2 PSE
Can only be powered locally (local power provided by the backplane of the TeleLite
shelf)
Has DIP switches to set:
Master/Slave
Types 1 or 2
MDIX enabling or disabling (“Disabled”is default). Check modems if they are
MDIX enabled. If they are not, this feature should be enabled to avoid cross-
over issues.
PSE enabling or disabling depending on if the terminating modem is locally
powered or not. If modem is not locally powered, set this DIP switch (#4) to the
“Enabled”
1.3.3 Ethernet Modem Interface Card Features:
Support of single- and multi-mode ST/SC connector type.
POE CFJ card can be either remote or locally powered through a jumper setting.
The modem/switch ports are auto-sensing with the hardware automatically detecting
and setting the speed for any 10 Base-T/100 Base-TX device connected to the
interface.
Auto-negotiation for half/full duplex operation on every port automatically.
Auto Uplink takes care of the MDI/MDI-X connection and eliminates the need for toggle
switches or special crossover cables on all 10/100 ports. This results in automatic
polarity correction that helps find and fix common cabling problems.
Flow control ensures reliable communications during full-duplex operation.
Unmanaged switch function provides plug-and-play simplicity.
Comprehensive LED display with per-port indicators allows status monitoring and
activity of every port at a glance.
Switch design delivers dedicated bandwidth to each port.
100mbps of Ethernet through-put is shared equally among the RJ-48 receptacles used

2.0 Type 1 and Type 2 TeleLite Ethernet Configurations
An Ethernet configuration requires two cards; usually a Power Over Ethernet (POE) and Power
Serving Ethernet (PSE), however the same TeleLite Ethernet card can be used at each end of the
fiber span between the CFJ (Copper Fiber Junction) and Optical Electrical Interface depending on
local power arrangements, Network Ethernet Edge Devices and the terminating Ethernet modems.
2.1 Type 1a and Type 1b, General
In a Type 1a configuration, the TeleLite Ethernet card at the Central Office (C.O.) as the CFJ
(Copper Fiber Junction) and interfaces with the network Edge Devices, providing the Ethernet
service.
In a Type 1b configuration, the TeleLite Ethernet card as the CFJ (Copper Fiber Junction) is
located at the 300v Point of the GPR contour of the electric supply location and interfaces with the
network Edge Devices, providing the Ethernet service. See Figures 1 & 2.

Type 2b describes multiple 10 Base-T / 100 Base-TX single port networked modems feeding a
TeleLite Ethernet card to distribute network connectivity to remote devices. See Figures 5 and 6.
2.3 DIP Switch Settings on POE and PSE TeleLite Ethernet Cards
The setting of the on-board DIP switches is dependent on the application. In general, there are
several things to take into account:
Is it a Type 1a, Type 1b, Type 2a, or Type 2b scenario?
Which of the two cards is to be set to master and which to slave
Is the modem feeding, or being fed by, the TeleLite Ethernet MDIX enabled?
What POE and PSE settings best suit the application of the cards?

2.3.1 Type 1a: 720930xxx TeleLite POE Ethernet Card
Located at the Central Office (CFJ)
(Note: Default DIP Switch Settings are shown in Figure 8)
A. If the 720930xxx POE Ethernet card is to be powered by C.O. battery (-48Vdc) then the two on-
board Power Option Jumpers should be set in the LOCAL PWR position. (Figure 7)
B. If the 720930xxx card was to be powered by POE at the C.O. (or CFJ) the Power Option Jumpers
are to be set to the remote power (RMT PWR) positions. (Figure 7)
C. If the 720930xxx TeleLite POE card is placed in the Central Office (C.O.) and is feeding Ethernet to
a remote, unmanned site, such as a solar farm, the Master and Slave switches should be set so
that the 720930xxx card is set as Master, and the companion 720920xxx card located at the OEI
(Optical Electrical Interface) is set as Slave. Alarms will be reported to the manned 720930xxx
located at the Central Office. (Figure 9)
D. If this is a Type 1 Ethernet deployment as described in Section 1.3.1, the 2nd DIP switch should be
set to the left. (Figure 9)
E. If the Ethernet modem that is feeding the TeleLite modem, or is being fed by the TeleLite Ethernet
cards is MDIX enabled(1), then the MDIX feature of the TeleLite Ethernet card should be disabled. If
the associated modems are NOT MDIX enabled, then this DIP switch should be enabled to remove
any need for crossover cables. With this feature enabled or disabled appropriately, there is never a
need with TeleLite Ethernet cards to provision the site with anything but a straight CAT 5 cable. In
this example the Ethernet Modem is MDIX enabled and the feature on the TeleLite Ethernet card is
disabled. (Figure 9)
F. Since the 720930xxx is a POE Ethernet card, the PSE DIP Switch (4th) on this card should always
be in the PSE Disabled position. (Figure 9)
1Ethernet over twisted pair defines a medium dependent interface crossover (MDI-X) interface. Auto MDI-X ports on newer
network interfaces detect if the connection would require a crossover, and automatically chooses the MDI or MDI-X configuration
to properly match the other end of the link.

2.3.2 Type 1b: 720930xxx TeleLite POE Ethernet Card
Located at CFJ, placed at the 300V point of the Substation’s GPR Contour
(Note: Default DIP Switch Settings are shown in Figure 11)
A. If the 720930xxx POE Ethernet card is to be powered by a local supply of -48Vdc, then the
two on-board Power Option Jumpers should be set in the LOCAL PWR position. (Figure 10)
B. If the CFJ is located as mentioned above, it is highly likely that the TeleLite 720930xxx
Ethernet card will be powered using POE and the Power Option Jumpers should be set to the
remote power (RMT PWR) positions unless local a -48Vdc source is used instead. (Figure 10)
C. If the 720930xxx TeleLite POE card is placed as a CFJ at the 300V point of the Substation’s
GPR Contour, and then is feeding Ethernet via fiber to an OEI located at a generation or
distribution substation, such as at a solar farm, the Master and Slave switches should be set
so that the 720930xxx card is set as Slave, and the companion 720920xxx card located at the
OEI (Optical Electrical Interface) is set as Master. If the OEI at the solar farm is the manned
location and set as Master, the alarms will report to the 720920xxx at the OEI from the
720930xxx at the CFJ. (Figure 12)
D. If this is a Type 1 Ethernet deployment as described in Section 1.2.1, the 2nd DIP switch
should be set to the left. (Figure 12)
E. If the Ethernet modem that is feeding the TeleLite modem, or is being fed by the TeleLite
Ethernet cards is MDIX enabled(2), then the MDIX feature of the TeleLite Ethernet card should
be disabled. If the associated modems are NOT MDIX enabled, then this DIP switch should be
enabled to remove any need for crossover cables. With this feature enabled or disabled
appropriately, there is never a need with TeleLite Ethernet cards to provision the site with
anything but a straight CAT 5 cable. In this example the Ethernet Modem is MDIX enabled and
the feature on the TeleLite Ethernet card is disabled. (Figure 12)
F. Since the 720930xxx is a POE Ethernet card, the PSE DIP Switch (4th) on this card should
always be in the PSE Disabled position. (Figure 12)
2Ethernet over twisted pair defines a medium dependent interface crossover (MDI-X) interface. Auto MDI-
Xports on newer network interfaces detect if the connection would require a crossover, and automatically chooses
the MDI or MDI-X configuration to properly match the other end of the link.

2.3.3 OEI for Type 1a or Type 1b
720920xxx TeleLite PSE Ethernet Card Located at the Substation OEI
(Note: Default DIP Switch Settings are shown in Figure 13)
A. The 720920xxx POE Ethernet card can only be locally powered by a source of -48Vdc. As such
there are no power jumpers to set on this card.
B. The 720920xxx TeleLite PSE card is placed at the Substation’s OEI. If this location is likely to
be manned, the Master and Slave switches should be set so that the 720930xxx card is set as
Slave (See Type 1b, 720930xxx), and the companion 720920xxx card located at the OEI
(Optical Electrical Interface) is set as Master. Alarms will be reported to the attended 720920xxx
located at the OEI at the substation OEI. (Figure 14)
C. If this is a Type 1a or Type 1b Ethernet deployment as described in Section 1.2.1, the 2nd DIP
switch should be set to the left. (Figure 14)
D. If the Ethernet modem fed by the 720920xxx PSE TeleLite Ethernet cards is MDIX enabled(3),
then the MDIX feature of the TeleLite Ethernet card should be disabled. If the associated
modems are NOT MDIX enabled, then this DIP switch should be enabled to remove any need
for crossover cables. With this feature enabled or disabled appropriately, there is never a need
with TeleLite Ethernet cards to provision the site with anything but a straight CAT 5 cable. In this
example the Ethernet Modem is MDIX enabled and the feature on the TeleLite Ethernet card is
disabled. (Figure 14)
E. If the 720920xxx card is to provide PSE to a terminating modem, the 4th DIP Switch is set to the
left. If the Ethernet modem at the OEI is locally powered by a source of -48Vdc, then the 4th DIP
switch is set to the right. (Figure 14)
In this example, the Ethernet modem at the OEI location is powered via the PSE output from the 4
ports on the faceplate of the 720920xxx TeleLite Ethernet card. (Figure 15)
3Ethernet over twisted pair defines a medium dependent interface crossover (MDI-X) interface. Auto MDI-
Xports on newer network interfaces detect if the connection would require a crossover, and automatically chooses
the MDI or MDI-X configuration to properly match the other end of the link.

2.3.4 Type 2a and Type 2b TeleLite “Campus” Configuration
In a “Campus” Deployment of Ethernet, the TeleLite Ethernet cards are used to transport and
distribute on-site Ethernet services to other buildings or facilities were it is desired to use fiber
instead of copper to carry the Ethernet traffic, either because of the distance limitation on copper or
electrical potential differences. A single multi-port modem or several individual modems can feed
the TeleLite Ethernet card. The actual location may be fed from a network by copper or fiber. See
Figure 16.

2.3.5 Type 2a and Type 2b, POE
720930xxx TeleLite POE (CFJ) Ethernet Card Fed by On-Site Modem
A. If the 720930xxx POE Ethernet card is to be powered by a local source of -48Vdc then the
two on-board Power Option Jumpers should be set in the LOCAL PWR position. (Figure
17)
B. If the 720930xxx card was to be powered by POE from the feeding modem (or CFJ) the
Power Option Jumpers should be set to the remote power (RMT PWR) positions. (Figure
17)
C. In a “Campus” Ethernet transport configuration, either the OEI (720920xxx) or CFJ
(720930xxx) can be set to Master or Slave since both ends of the transport can be
assumed to be attended for alarming purposes. The only criterion is that one card must be
set to Slave and the other to Master. (Figure 19) In this example, the CFJ (720930xxx)
TeleLite Ethernet card has been set as Master.
D. This is a Type 2 (a or b) deployment so the 2nd DIP switch should be set to the right,
accordingly. (Figure 19)
E. If the Ethernet modem that is feeding the TeleLite Ethernet card or that is being fed by the
TeleLite Ethernet cards is MDIX enabled(4), then the MDIX feature of the TeleLite Ethernet
card should be disabled. If the associated modems are NOT MDIX enabled, then this DIP
switch should be enabled to remove any need for crossover cables. With this feature
enabled or disabled appropriately, there is never a need with TeleLite Ethernet cards to
provision the site with anything but a straight CAT 5 cable. In this example the Ethernet
Modem is MDIX enabled and the feature on the TeleLite Ethernet card is disabled. (Figure

F. Since the 720930xxx is a POE Ethernet card, the PSE DIP Switch (4th) on this card should
always be in the PSE Disabled position. (Figure 19)

Xports on newer network interfaces detect if the connection would require a crossover, and automatically chooses
the MDI or MDI-X configuration to properly match the other end of the link.

2.3.6 Type 2a and Type 2b, PSE
720920xxx TeleLite PSE (OEI) Ethernet Card Feeding On-Site Modem(s)
A. The 720920xxx POE Ethernet card can only be locally powered by a source of -48Vdc. As
such there are no power jumpers to set on this card.
B. In a “Campus” Ethernet transport configuration, either the OEI (720920xxx) or CFJ
(720930xxx) can be set to Master or Slave since both ends of the transport can be
assumed to be attended for alarming purposes. The only criterion is that one card must be
set to Slave and the other to Master. In this example, the CFJ (720930xxx) TeleLite
Ethernet card has been set as Master. (See 1.5.4.1) This 720920xxx OEI Ethernet card
has been set as Slave. (Figure 23)
C. If this is a Type 2a or Type 2b Ethernet deployment as described in Section 1.5.4, the 2nd
DIP switch should be set to the left. (Figure 23)
D. If the Ethernet modem fed by the 720920xxx PSE TeleLite Ethernet cards is MDIX
enabled(5), then the MDIX feature of the TeleLite Ethernet card should be disabled. If the
associated modems are NOT MDIX enabled, then this DIP switch should be enabled to
remove any need for crossover cables. With this feature enabled or disabled appropriately,
there is never a need with TeleLite Ethernet cards to provision the site with anything but a
straight CAT 5 cable. In this example the Ethernet Modem is MDIX enabled and the feature
on the TeleLite Ethernet card is disabled. (Figure 23)
E. If the 720920xxx card is to provide PSE to a terminating modem, the 4th DIP Switch is set
to the left. If the Ethernet modem at the OEI is locally powered by a source of -48Vdc, then
the 4th DIP switch is set to the right. In this example, PSE is enabled. (Figure 23)
5Ethernet over twisted pair defines a medium dependent interface crossover (MDI-X) interface. Auto MDI-
Xports on newer network interfaces detect if the connection would require a crossover, and automatically chooses
the MDI or MDI-X configuration to properly match the other end of the link.
