Figure 1: VRM01/24

The VRM01/24 has 24 x POTS Ports(RJ21)24 x 12.5 Mbps VDSL Ports (RJ21)

1 x 10/100/1000Mbps auto-sensing RJ-45 and 1 x Giga RJ-45/GBIC(fiber optic) Auto-Link

Ethernet port . The VRM01/24 is one rack-unit (1RU) high, 14-inches deep. It is a standard 19”

Rack mounted size.

the VRM01/24 deliver dedicated bandwidth per port at rates up to 12.5 Mbps. VDSL

transmissions coexist with POTS and ISDN, and can be compatibled with ADSL/HomePNA

traffic in the same building. The VRM01/24 can be configured on a per-switch basis to support

the following modes:

12.5 Mbps symmetrical rate (up to 1200 meter/4000 Feets)

The VRM01/24 and VDSL Modem provide fast and easy connectivity into building patch panels

with RJ-21 connector. The 10/100/1000 Ethernet ports can be used to connect servers, Ethernet

switches. These connectivity options provide multiple price/performance options to meet building

and budget requirements.

The VRM01/24 provides the important features necessary for robust networks:

Quality of Service: 802.1p COS supports. Provides high-and low-priority queuing on a

per-port basis.

Supports: IGMP Snooping by 512 IP multicast table for VOD (Video on demand)

Scalability: Up to 10 Mbps symmetric performance over single-pair wiring. Fast

Ethernet Channel port aggregation.

Security:802.1Q Tag base and port-based virtual local-area network (VLAN) support. Private

VLAN access, assuring port security without requiring a VLAN per port, and also supports MAC

filtering to Lock MAC address.

Network Management: VDSL VRM01/24 technology support Telnet and Web-based

Management easy-to-use configuration and ongoing monitoring. This software is embedded in

the VDSL VRM01/24 and delivers remote, intuitive management of VDSL VRM01/24 and

connected VDSL CPE devices through a single IP address.

The VRM01/24 are easy-to-configured and deployed, and offering a compelling option in terms

of cost, performance, scalability and services compared to traditional ATM-based xDSL

2. General Description

Hardware Description

This section describes the important parts of the VRM01/24. It features the front and rear

panel drawings LEDs, connectors, and switchs.

Front Panel

The following figure shows the front panel.

Figure Chapter 2.1 Front Panel description

Front panel.

(1) “PWR.”: Power Led light.

(2) “POST”: Power On Self Test.

(3) 24XPOTS Ports(RJ21).

(4) 24X10 Mbps VDSL Ports (RJ21).

(5) RS-232 Console Port.

(6) 1 x 10/100/1000Giga RJ-45/GBIC(fiber) Auto-Link Ethernet port

(7) 1X10/100/1000 Mbps auto-sensing N-way Ethernet ports.

(8) Reset Button.

the VRM01/24 has embedded Splitter between every VDSL side and POTS side. It permit

you can delivers broadband service on the same lines as Plain Old Telephone Service

(POTS), PBX, ISDN traffic and VDSL Signal.

Several LED indicators for monitoring the device itself, and the network status. At a quick

glance of the front panel, the user would be knew if the product is receiving power; if it is

monitoring another VRM01/24 or other devices; or if a problem exists on the network.

VDSL SERIES CTC Union

Provides one 10/100/1000Mbps auto-sensing RJ-45 Ethernet ports and one GIGA Port.

GIGA Port support RJ-45 or GBIC Interface auto link function. You can use RJ-45 interface or

GBIC

interface.Figure Chapter 2.2

Normal GIGA port status default in copper (RJ45), if you want to change connect media to

fiber you must plug in GBIC fiber module.

First, make sure fiber to fiber connecting is ready, and another fiber device must power on first,

then reboot VRM01/24, that will be sensing and link that in Fiber optic mode.

GIGA port RJ-45 and GBIC can’t use in the same time,else that will be link in Copper

mode(default).

If you want to change GIGA port interface (RJ45 interface link change to

GBIC interface link or GBIC interface link change to RJ45 interface link), you must reboot system

again.

GBIC Fiber Optics

A gigabit interface converter (GBIC) is a transceiver that converts electric currents (digital

highs and lows) to optical signals, and optical signals to digital electric currents. The GBIC is

typically employed in fiber optic and Ethernet systems as an interface for high-speed

networking. The data transfer rate is 1.25 gigabit per second.

GBIC modules allow technicians to easily configure and upgrade electro-optical

communications networks. The typical GBIC transceiver is a plug-in module that supports

hot-plugging (it can be removed and replaced without turning off the system). The devices

are economical, because they eliminate the necessity for replacing entire boards at the

system level. Upgrading can be done with any number of units at a time, from an individual

module to all the modules in a system. GBIC(Gigabit Interface Converter), meet the Gigabit

Interface Converter specification Rev. 5.4 (MOD_DEF4) industry standard.
