NetComm NCT240 Installation Guide Release 1.0
1. Introduction
This document is intended for First Office Acceptance test plan for NetComm’s ADSL2+ Broadband Access Switch solution (BAS). The Netcomm NCT240 Broadband Access Switch
contains 24 ADSL2/2+ circuits to deliver high-speed data, video and voice service over traditional twisted copper pairs by using DSL technology.
To meet the increasing demand for high-speed internet access and triple play application services. The next generation network offers a feasible functionality of integrated ser vices with the most cost effective architecture. Next generation broadband access networks are designed to provide rich video contents, DSL, POTS and VoIP services over traditional copper wire infrastructure. These types of services will be supported on NGN architecture simultaneously. DSL is used as the data service platform for traditional POTS technology which is used for voice services. The multimedia and local content-rich applications can also be easily implemented on this NGN architecture.
xDSL (Digital Subscriber Line) is a technology for delivering high-bandwidth information over copper telephone lines. xDSL service can deliver POTS and high date rate services simultaneously over a single twisted-wire pair. The POTS and data service are simultaneous and independent; the xDSL data service does not affect the POTS service. xDSL uses the bandwidth above the 4-kHz POTS frequency to transmit duplex data using digital modulation techniques from the C.O side to the Customer Premises Equipment (CPE).
ADSL is a form of xDSL service that delivers an asymmetric data rate over a twisted copper pair. ADSL delivers a higher rate downstream, towards the customer premises and lower rate upstream, from the customer premises. ITU standard compliant Full-Rate ADSL2+ can deliver data rates up to 25 Mbps downstream and 1 Mbps upstream; Full-Rate ADSL can deliver data rates up to 8 Mbps downstream and 800 kbps upstream; G.Lite ADSL can deliver up to 1.5 Mbps downstream and 512 kbps upstream. The actual data rate depends on the length, gauge, and condition of the twisted-wire pair, the bandwidth of the uplink depends on the data network, and the capacity of the network service provider.
Digital Subscriber Line (DSL) dominates broadband market. The position of national telecom operators in most countries has given the advantage in reaching out to customers with broadband services over DSL.
The NCT240 Access system contains 24 ADSL2/2+ circuits to deliver high-speed data service over twisted copper pairs using industry standard Discrete Multi-Tone (DMT) line coding technology. The NCT240 complies with full-rate ADSL in accordance with ANSI T1.413 Issue 2, ITU-T G.992.1 (G.dmt), ITU-T G.992.2 (G.lite)ITU-T G.992.3 ( ADSL2) and ITU G.992.5 (G.ADSL2+) protocols.
The NCT240 greatly expand broadband capabilities in the access network, enhancing the infrastructure for emerging servic es. With simple in-service upgrades, service provid ers obtain the capacity and Quality of Service (QoS) to support larger populations of narrowband and broadband users. For management, NCT240 can be easily configured by SNMP, T elnet, SSH, HTTP, HTTPS and RS-232 console.

The NCT240 may be mounted on any flat surface, such as a shelf, or in a rack. Before you start installing the access switch, make sure you can provide the right operating environment, including power requirements, sufficient physical space, and proxim ity to other network devices that are to be connected. Verify the following installation requirements:
• Power requirements: 100 to 240 VAC (± 10%) at 50 to 60 Hz (± 3 Hz). The access switch power
supplies automatically adjust to the input voltage level. Make sure that a properly grounded power outlet is within 2.5 m (8 ft) of the access switch.
• The access switch should be located in a cool dry place, with at least 10 cm (4 in.)of space on
the sides for ventilation.
• Place the access switch out of direct sunlight, and away from heat sources or areas with a high
amount of electromagnetic interference. The temperature and humidity should be within the ranges listed in the specifications.
• If you intend to mount the access switch in a rack, make sure you have all the necessary
mounting screws, brackets, bolts and nuts, and the right tools.
• Check if network cables and connectors needed for installation are available.

Proper grounding (earth)
Proper Grounding is a very important part of the electrical installation for NCT240, if noise is present in the Electrical ground this noise can leak to the ADSL circuit through the Surge protectors and interfere with the proper operation of ADSL links.
*** both AC/DC power supplies are isolated from the NCT240 ground therefore the Grounding procedure is the same regardless of what the power supply is .

Installing an SFP Transceiver
NCT240
Figure 4-5. Inserting an SFP Transceiver into the Slot
To install an SFP transceiver, do the following:
1. Use your cabling requirements to select an appropriate SFP transceiver type.
2. Insert the transceiver with the LC connector facing outward and the slot connector facing
down. Note: SFP transceivers are keyed so they can only be installed in one orientation.
3. Slide the SFP transceiver into the slot until it clicks into place.
Notes:
1. If the stacking ports are connected, the SFP port will be disabled.
2. SFP transceivers are hot-swappable. You do not need to power off the switch before
installing or removing a transceiver. However, you should always first disconnect the network cable before removing a transceiver.
Connecting to the 1000BASE-T and 10/100BASE-TX Interface
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. For 1000BASE-T connections, Category 5, 5e or better cable is required; for 100BASE-TX
connections, Category 5 cable is required; for 10BASE-TX, Category 3,4, or 5 cable can be used. The RJ-45 ports on the NCT240 modules support automatic MDI/MDI-X operation, so you can use
standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).
Note: Auto-negotiation must be enabled for automatic MDI/MDI-X pin out configuration. See
Appendix B for further information on cabling.
NetComm NCT240 Installation Guide Release 1.0
Connecting RJ-21 Cables
For incoming phone lines, a splitter can connect directly to a PBX or can be connected via a punch-down block. The particular connection method used will depend on the type of connectors and cables supported on the PBX, and on the existing cabling in the building. The EE lines from the splitter interface of NCT240 are connected to the punch-down block that connects the phone lines that run up to the end users. If the NCT240 is installed in a rack, it may be convenient to use a patch panel between the splitter interface and the punch-down block.
For all connections to the splitter interface, cables with standard Telco RJ-21 connectors must be used. Some punch-down blocks can be pre-wired with an RJ-21 connector provided, making the connection simple. Otherwise, a cable with an RJ-21 on one end and free wi ring on the other end will be required.
Figure 4-6. Connecting to the Punch-down Blocks
Follow the steps below to connect an EE Splitter to a building’s phone-line system using a punch-down block:
1. Connect one RJ-21 flat cable from the PBX to the connector on the splitter’s rear panel
labeled “PBX/MDF.” Note: Some installations may also have a separate punch-down block between the PBX and the
EE Splitter. In this case, connect an RJ-21 cable from the splitter’s “PBX/MDF” connector to the punch-down block.
2. Connect another RJ-21 flat cable from the RJ-21 connector on the front of the splitter labeled
“Line” to the building’s phone-line punch-down block. Note that the connection to the punch-down block usually requires punching down the free wires from the RJ-21 cable. Note: If you use pre-wired punch-down blocks with RJ-21 connectors, be sure they are wired to
match the pin assignments of ports on the back of the splitter. To ensure that your cables are properly wired, refer to “RJ-21 Port Pin Assignments” on page B-6.

10BASE-T/100BASE-TX Pin Assignments
For 100BASE-TX/10BASE-T connections, a twisted-pair cable must have two pairs of wires. Each wire
pair is identified by two different colors. For example, one wire might be red and the other, red with white
stripes. Also, an RJ-45 connector must be attached to both ends of the cable.
With 100BASE-TX/10BASE-T cable, pins 1 and 2 are used for transmitting data, and pins 3 and 6 for
receiving data.

Because the ports on the NCT240 support automatic MDI/MDI-X operation, you can use
straight-through cables for all network connections to PCs or servers, or to other switches or hubs. In
straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1,
2, 3 and 6 at the other end of the cable. The table below shows the 10BASE-T/100BASE-TX MDI and
MDI-X port pin outs.

Note: Auto-negotiation must be enabled for automatic MDI/MDI-X pinout configuration.
1000BASE-T Pin Assignments
1000BASE-T ports support automatic MDI/MDI-X operation, so you can use straight-through cables for
all network connections to PCs or servers, or to other switches or hubs. The table below shows the
1000BASE-T MDI and MDI-X port pinouts. These ports require that all four pairs of wires be connected.
Note that for 1000BASE-T operation, all four pairs of wires are used for both transmit and receive. Use
100-ohm Category 5, 5e or better unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for
1000BASE-T connections. Also be sure that the length of any twisted-pair connection does not exceed 100
meters (328 feet).
