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

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

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.
