Introduction to
netAccess L-Series
Introduction to netAccess L-Series
The netAccess L-Series is a family of versatile financial payment routers, capable of
supporting multiple payment devices in a LAN environment, providing a variety of
connectivity options to provide high availability connection to the main payment backbone.
With its compact form factor, the L-Series device can be placed discreetly at payment
counters or cash registers to connect several payment devices to the payment host.
The netAccess L-200 series
The L-200 series is designed for a medium sized merchant environment to connect up to 10
terminals using the usual transports such as RS232, RS485 and TCP/IP through a single GPRS
channel. The L-200 model supports 2 SIM cards to ensure the communications are not
affected by failure of the primary mobile network. The device will automatically switch from
primary SIM to the secondary SIM if the primary network goes down.

netAccess L-200 Series Manual 32 | Page
Scenario 1: L-50 serving 3 PSTN Terminals
Figure 30: Deployment of L-50 POS-PBX
Setup:
A merchant with 3 PSTN terminals can use the L-50 to connect all 3 terminals to the
acquiring bank using GPRS. Instead of having 3 separate phone lines or splitting a single
phone line into 3 extensions, all 3 terminals are connected to the POS-PBX Hydra Smart
Connector plugged into the L-50. The terminals dial normally and the L-50 will convert the
signal into TCP/IP protocol and send it to the host over GPRS for approval.
Advantages:
Single GPRS connection serves up to 3 terminals.
Terminal application does not have to be changed.
Cost savings in terms of line rental and call charges: For a low fixed cost, a 2 MB
GPRS package from the mobile operator is sufficient to cater for a moderately busy
outlet that does around 100 transacations a day or 4000 transactions a month.
Note: Transactions are assumed to be an average 500 bytes in size.
Considerations:
The L-50 can only support one outgoing connection at any given time so it is not
suitable for high volume sites. It is intended to allow the merchant to share one
GPRS connection among 3 PSTN terminals with no modifications required on the
terminal.
Page 38
netAccess L-200 Series Manual 33 | Page
Scenario 2: L-200 Optimus converts PSTN to GSM/GPRS
Figure 31: L-200 Optimus connects up to 3 terminals and one telephone
Setup:
A merchant with 3 PSTN terminals can use the L-200 Optimus to connect all 3 terminals to
the acquiring bank using GPRS. Instead of having 3 separate phone lines or splitting a single
phone line into 3 extensions, all 3 terminals are connected to the POS-PBX Hydra Smart
Connector plugged into the L-200 Optimus. The terminals dial normally and the L-200
Optimus will convert the signal into TCP/IP protocol and send it to the host over GPRS for
approval. In addition to that, with the netAccess L-200 Optimus, he can also connect a
telephone set to the device, while using a single mobile telephone SIM card to fulfill his
communcations needs.
Advantages:
Single GPRS connection serves up to 3 terminals and one single-line phone.
Terminal application does not have to be changed.
Cost savings in terms of line rental and call charges: For a low fixed cost, a 2 MB
GPRS package from the mobile operator is sufficient to cater for a moderately busy
outlet that does around 100 transacations a day or 4000 transactions a month.
Note: Transactions are assumed to be an average 500 bytes in size.
Considerations:
The L-200 Optimus can only support one outgoing connection at any given time.
Transactional data takes precedence over voice calls – therefore, if a voice call is in
progress when a transaction is initiated, the phone set will beep 3 times and the
voice call will disconnect in 3 seconds.
Page 39
netAccess L-200 Series Manual 34 | Page
Scenario 3: L-100 as a Port Extender
Figure 32: L-100 with 3 connected RS232 devices
Setup:
The netAccess L-100 can be used to extend the number of RS232 ports available for a retail
POS setup to overcome the limited number of serial RS232 ports for device integration. The
Electronic Cash Register (ECR) is connected using RS232 to a Terminal and a Contactless
Reader. Purchases are totaled on the ECR. The amount to pay appears on the ECR and is also
displayed on the Contactless Reader. The customer has a choice of Contactless or
Credit/Debit Card (Contact Cards). The payment is processed by the terminal and sent
through the netAccess L-100 to the Acquiring Host over GPRS or ADSL for authorization and
the response returned to the terminal and ECR.
Advantages:
Allows up to 3 RS232 devices to be connected together.
If using TCP/IP terminals, the L-100 supports up to 5 TCP/IP terminals
If using RS485 terminals, the L-100 supports up to 5 RS485 terminals
Cost savings in terms of line rental and call charges – For a low fixed cost, a 2 MB
GPRS package from the mobile operator is sufficient to cater for a moderately busy
outlet that does around 100 transacations a day or 4000 transactions a month.
Suitable for small merchants who want an integrated, cost-saving setup.
Existing RS232 terminals can be reused for this setup, no need to upgrade to TCP/IP
or GPRS terminals.
TCP/IP terminals can be placed further away than RS232 terminals, useful for a
second or third counter.
Considerations:
Connection is via GPRS or ADSL or Leased Line only – all three cannot be used
concurrently.
Although the L-100 supports up to 5 device connections, RS232 connections are
limited to 3 devices only.
Page 40
netAccess L-200 Series Manual 35 | Page
Scenario 4: L-100 as a Wireless Concentrator
Figure 33: Five RS485 or TCP/IP terminals connected to Acquiring Host via GPRS
Setup:
The netAccess L-100 can connect 5 RS485 serial terminals or 5 TCP/IP terminals to the
Acquiring Host over GPRS. The L-100 acts as a transaction concentrator that channels all the
transactions through a single GPRS connection to the Acquiring Host.
This setup is useful for offsite, temporary locations such as road shows or concourse
promotions run by merchants outside of their premises or medium sized merchants wanting
to save on communications costs.
Advantages:
The L-100 supports up to 5 TCP/IP terminals OR 5 RS485 terminals.
The L-100 acts as a transaction concentrator – transactions from multiple terminals
are channeled through a single GPRS or ADSL connection to the host.
Does not require PSTN lines or other wired communications, suitable for temporary
setups such as road shows.
Both TCP/IP and RS485 protocols support longer cable lengths compared to RS232 –
paymentpointscanbemorespreadoutforcustomers’convenience.
Cost savings in terms of line rental and call charges – For a low fixed cost, a 2 MB
GPRS package from the mobile operator is sufficient to cater for a moderately busy
outlet that does around 100 transacations a day or 4000 transactions a month.
Suitable for small to medium sized merchants.
Considerations:
Connection is via GPRS or ADSL or Leased Line only – all three cannot be used
concurrently.
The L-100 supports a maximum of 5 device connections only, which can be a
combination of RS232 (maximum 3 devices), RS485 and TCP/IP. If more than 5
connections are required, consider using either the L-300 or L-350 devices.

netAccess L-200 Series Manual 36 | Page
Scenario 5: L-200 in a Multi-lane Deployment with Dual GPRS
Figure 34: L-200 with 10 connected RS485 or TCP/IP terminals via GPRS
Setup:
The netAccess L-200 can connect 10 serial (RS485 or TCP/IP) terminals to the Acquiring Host
over GPRS. Higher avaialability is provided by second GPRS SIM. Like the L-100, it is a
transaction concentrator that channels all the transactions through a single GPRS
connection to the Acquiring Host, with the addition of a backup SIM card. If GPRS #1 goes
down, GPRS #2 will take over automatically. Only one SIM is active at any time. This setup is
useful for medium sized merchants who have multiple payment counters who cannot
tolerate downtime due to network problems.
Advantages:
The L-200 supports up to 10 TCP/IP terminals or 10 RS485 terminals.
The L-200 acts as a transaction concentrator – transactions from multiple terminals
are channeled through a single GPRS or ADSL connection to the host.
Does not require PSTN lines or other wired communications, except as backup.
Both TCP/IP and RS485 protocols support longer cable lengths compared to RS232 –
paymentpointscanbemorespreadoutforcustomers’convenience.
Cost savings in terms of line rental and call charges –A GPRS data package from the
mobile provider is a fixed cost compared to the variable costs of PSTN lines.
Dual SIM provides robust connectivity.
Suitable for small to medium sized multi-lane merchants.
Connection is via GPRS or ADSL or Leased Line only – all three cannot be used
concurrently.
Considerations:
The L-200 supports a maximum of 10 device connections only, which can be a
combination of RS232 (maximum 3 devices), RS485 and TCP/IP. If more than 10
connections are required, consider using either the L-300 or L-350 devices.
Page 42
netAccess L-200 Series Manual 37 | Page
Scenario 6: L-300 or L-350 VPN connection over GPRS
Figure 35: L-350 connected to host through VPN tunnel on GPRS
Setup:
The netAccess L-300/L-350 is capable of establishing a VPN tunnel over GPRS. This requires a
VPN Gateway server to be located in the Acquirer’s premises and this server must have
access to the Host.
Advantages:
Up to a maximum of 15 (for L-300) or 30 (for L350) devices can be connected.
Suitable for multi-lane environments or large merchant.
VPN tunnel provides higher level of security over Public Internet (GPRS).
L-350 comes with Dual SIM for redundant GPRS link.
Cost savings in terms of line rental and call charges –A GPRS data package from the
mobile provider is a fixed cost compared to the variable costs of PSTN lines.
Lower cost than traditional Leased Line connections.
Considerations:
A key management infrastructure will be required to manage the keys for the VPN
encryption. The key management infrastructure needs to support key revocation
and key rollover.

netAccess L-200 Series Manual 38 | Page
High Availability Configurations
The netAccess L-Series devices are designed to ensure the connection to the acquiring host
is robust and stable. This high availability is managed by the NetRouter service. The
NetRouter service is configured with a list of available uplink channels, in the order of
preference. (Usually in the order of cost or speed). A typical uplink channel preference list
looks like this:
1) ADSL or Leased Line8
2) GPRS
3) PSTN
The NetRouter service uses a combination of channel-specific failure detection mechanisms
andan“x-consecutive-transaction-timeouts”algorithm to detect when a channel is down.
Whenanuplinkchannelisdetectedas“down”,theNetRouterservicewillroutesubsequent
transactions to the next available channel defined in its failover list. The downed channel is
polled periodically until the connection is re-established. The connection is monitored and
once stabilized, it is marked as “up”, and subsequent transactions are routed through it
once more.
There are two types of channels:
Channel Type
Example
Notes
Permanent Links
Leased Line, ADSL, GPRS
Connection is permanent and may be
monitored by network monitoring
systems for link failure.
On-Demand Links
Dialup – either ISDN or
PSTN
Connection established when needed.
Failure detected only when used.
Usually only used as backup link in case
a permanent link goes down.
8
Additional hardware is required to support ADSL or Leased Line connections. This may include routers.
Page 44
netAccess L-200 Series Manual 39 | Page
Scenario 7: 3 levels of failover connections
Figure 36: L-350 with 3 levels of connection failover
Setup:
The netAccess L-300/L-350 can be configured for multiple levels of channel failover. In
the example above, the primary channel is Leased line or ADSL, followed by GPRS
followed by PSTN Dialup on demand. For the netAccess L-350 – an additional GPRS link
can be configured to backup the primary GPRS link. If the Leased Line or ADSL is down,
the GPRS will take over. If the GPRS fails, then the netAccess L-300 or L350 will initiate a
PSTN dialup to the Acquirer NAC and establish a low-speed connection to carry the
transactions. Depending on the configuration, the PSTN connection may be held (this
will be expensive) or dropped after an idle period and re-initiated upon the next
transaction received.
Advantages:
Up to maximum of 15 (for L-300) or 30 (for L-350) devices connected
Suitable for multi-lane environments or large merchant
L-350 comes with Dual SIM for redundant GPRS link
Cost savings in terms of line rental and call charges –A GPRS data package from the
mobile provider is a fixed cost compared to the variable costs of PSTN lines.
Lower cost than traditional Leased Line connections
Multiple channels ensure high availability of the acquiring host
Page 45
netAccess L-200 Series Manual 40 | Page
Scenario 8: L-200 Dual SIM GPRS failover
Figure 37: L350 with Dual SIM GPRS failover
Setup:
The netAccess L-200/L-350 supports Dual SIMs and can be configured to two levels of GPRS
channel failover. For models that support dual SIMs, an additional GPRS link can be
configured to backup the first GPRS link. If the main GPRS link is down, the second GPRS
channel will be activated to take over the link.
Advantages:
Up to maximum of 10 (for L-200) or 30 (for L350) devices connected
Cost savings in terms of line rental and call charges –A GPRS data package from the
mobile provider is a fixed cost compared to the variable costs of PSTN lines.
Lower cost than traditional Leased Line connections
Dual GPRS channels ensure high availability of the acquiring host with lower cost
than Leased Line connections
Considerations:
Dual SIM cards will double the cost of connectivity, but this is balanced against loss
of business due to loss of connectivity. Also, the operating cost of two SIM cards is
still less than the cost of a Leased Line.

Appendix B:
Pattern Matching
Conventions
Pattern matching strings are used to parse or filter route incoming messages for products
built on the netRouter engine. Based on the pattern, the message is then routed to an
assigned connection. A pattern matching string can be made up of a combination of
different patterns, with the pattern to be matched defined between the Pattern Header
string and Pattern Trailer string.
A pattern matching string consists of the following components:-
1B19 FF
Protocol Header
Pattern Header
Data Fields
Pattern Trailer

4Cxxxx
Data header length indicates that there is a header
that indicates length of the data field.
Example 1: 4C0280
There is a header length of 2 bytes (0280 in
Hexadecimal code) The message would look
something like:
00 0A 30 31 32 33 34 35 36 37 38 39
Where 000A (first 2 bytes) indicates there is 10 bytes
of data after the 2 byte header.

Examples of Patterns
Users should be able to configure the routing by reasonable mixing of the supported
pattern. Here are typical configuration patterns for pattern matching:
Rule for combining Patterns:
Each pattern should start with the Pattern Header (1B19) and end with the Pattern Trailer
(FF)
Patterns can be combined one after the other, in the sequence of processing.
