1 Overview
1.1 Product Introduction
VG Series intelligent VoIP Gateways (hereinafter called “VG Gateways” or simply “Gateways”) are
designed for the traditional telecom terminal devices to access IP networks through SIP or MGCP
protocols. Its main applications include:
zFor carriers and value-added service providers to provide telephone, fax and voice-band data
services to subscribers using IP access methods such as FTTB, HFC, and xDSL;
zUsed to bridge the traditional telecom terminal equipments, such as PBXs, to the IP core
networks of carriers;
zConnected with PBX of enterprises to provide IP-based voice private network solutions for
institutions, enterprises and schools;
zUsed as remote acces equipments for IP-PBXs in call center deployment.
VG Gateways are suitable for placement on office desktops or installation on walls in the corridor
and racks in the equipment room.
VG Series include VG1X, VG2X, VG100 and VG59X subseries. Their features are similar with the
main differences as follows:

VG Gateways use Freescale® PowerQUICC communications CPU series as main control processors
(including 60MHz MPC852T, 200MHz MPC8250 and 300MHz MPC8247) and TI’s
TMS320VC5509A high-performance digital signal processing chips as processors for voice and fax
processing (equipped with 1-14 DSP chips based on the need of concurrent call capacity), and are
integrated with 32MB-64MB SDRAM as system memory, 4MB-16MB FLASH as permanent file
system. The powerful processing capability and sufficient hardware configuration ensure that all
products of VG Series can provide concurrent calls of full capacity and maintain good call quality.
In terms of software, VG Gateways use stable and reliable embedded Linux operating system
matched with driver layers of different hardware platforms to realize the compatibility with full range
of application software products, ensuring the consistent functions and stable performance of the
product series.
VG Gateways support SIP and MCGP protocols. They can provide

There is a 6 × 4 LED indicator matrixes on the left side of interface board. Each row of LED
indicator matrixes matches four telephone lines on a RJ45. The first row on the left matches Line 1-4
respectively from top to bottom, the first row on the right matches Line 21-24 respectively from top
to bottom, and the middle rows in the same manner.
LED indicators are used for multiple purposes as follows
zLine status indication: This is the most common mode during normal use of equipment. In this
mode, if a line is idle, the indicator corresponding to it goes off; if a line is in call or in use status
(such as ringing, offhook and caller ID transmission of FXS interface, ringing, offhook and caller
ID detection of FXO interface) the indicator corresponding to it goes on.
zLine type indication: This is the mode for installation of equipment or wiring check. This mode
can be entered by disconnecting the network interface (two Ethernet interfaces on the host are
disconnected) when connecting lines at installation stage, or through interface control when the
check is made during normal operation. After entering the mode, LED constant on indicates that
the corresponding line is equipped and is an analog telephone line, LED flashing indicates that
the corresponding line is equipped and is an analog trunk lines; LED off indicates that the
corresponding line is not equipped or is faulty.
zSystem operation status indication: This is the mode for displaying information on system
operation of equipment in specific conditions. Usually, this mode is entered when some prompts

are required to give operator during equipment startup, diagnosis or operation. In this mode, LED
flashes to display numbers, letters or other patterns in matrix. Please refer to the Appendix:
Check List for Operation Status Indication of VG59X System.

VG59X single-chassis system can provide up to 48-line with different analog line type configuration
combinations, and VG59X dual-chassis system (main chassis and expansion chassis) can provide
maximum of 96-line with different analog line type configuration combination. VG59X dual-chassis
system is a logical integrated system formed by adding an expansion chassis and interface cards on
top of the single chassis system. Only an expansion cable is required to connect the two chassises,
and the original main chassis will not be affected when connecting the expansion cable, suitable for
on-site capacity expansion. The system resources (eg. number of concurrent calls) are completely
determined by the main chassis, so users who are planning to expand capacity should take into
account the needs for future system resources when initially ordering the single-chassis system, to
support the smooth capacity expansion and upgrade.

Numbering definition of system interface slots: On the left side of main chassis is #1 slot (marked
with ①in Figure 1-10), on the right side of main chassis is #2 slot (marked with ③in the Figure
1-10), on the left side of expansion chassis is #3 slot (marked with ②in the Figure 1-10), and on the
right side of expansion chassis is #4 slot, marked with ④in Figure 1-10).
Figure 1-11 Schematic Diagram for Back Panel of VG59X Dual-Chassis System
VG59X dual-chassis system consists of a main chassis and an expansion chassis. Seen from the front,
it is different from the screen-printed mark: main chassis printed with "VG59X-MAIN" mark and
expansion chassis printed with "VG59X-EXT" mark. Seen from the back, the difference is obvious:
expansion chassis does not have status indicator, USB interface, CON interface and two Ethernet
interfaces. The main and expansion chassises have their own independent power supply and cooling
system, which are connected by a 36-core flat cable to form a logical integrated system.
To ensure the reliable communications between two chassises and reduce EMI interference, the
communication cable for connecting two chassises should be short. VG59X dual-chassis system must
be placed adjacently in installation (users who plan to expand capacity should reserve a space for

VopTel Technology Co., Ltd Page 20/67
expansion chassis during the initial installation of single chassis), the up or lower position is not
strictly required for the chassises.
