Mediant 2000/SIP User’s Manual 1. Overview
Version 4.2 Beta 11 June 2003
1 Overview of the Mediant 2000
1.1 Introduction
AudioCodes’ Mediant 2000/SIP (Session Initialization Protocol) VoIP Gateway provides excellent
voice quality and optimized packet voice streaming over IP networks. The Mediant 2000/SIP
Gateway enables voice, fax, and data traffic to be sent over the same IP network.
Based on AudioCodes’ award-winning, field-proven TrunkPack design, the Mediant 2000/SIP
Gateway uses AudioCodes’ well-established DSP voice compression technology.
The Mediant 2000/SIP incorporates 1, 2, 4, 8 or 16 E1 or T1 spans for connection, directly to
PSTN telephony trunks, and includes one or two 10/100 Base-T Ethernet ports for connection to
the LAN.
The Mediant 2000/SIP supports up to 480 simultaneous Voice over IP (VoIP) or Fax over IP
(FoIP) calls, supporting various ISDN PRI protocols such as EuroISDN, North American NI2,
Lucent™ 5ESS, Nortel™DMS100 and others. In addition, it supports different variants of Channel
Associated Signaling (CAS) protocols for E1 and T1 spans, including MFC/R2, E&M immediate
start, E&M delay dial/start, loop start and ground start
The Mediant 2000/SIP Gateway, best suited for large and medium-sized VoIP applications, is a
compact device, 1 U high, installed in a 19-inch rack.
The deployment architecture can include several Mediant 2000/SIP Gateways in branch or
departmental offices, connected to local PBXs and call routing is performed by a centralized SIP
Proxy. Thus, the Mediant 2000/SIP VoIP Gateway enables users to make low cost long distance
or international telephone/fax calls between distributed company offices, using their existing
PBXs and telephones/fax. These calls are routed over existing IP Internet or Intranet corporate
data network(s). In addition, low bit-rate vocoders and silence suppression can be used, ensuring
that voice traffic takes the minimum of space on the data network.
The Mediant 2000/SIP can also route calls over the network using SIP signaling protocol,
enabling the deployment of "Voice over Packet" solutions in environments where access is
enabled to PSTN subscribers by using a Trunking Media Gateway. This provides the ability to
transmit voice and telephony signals between a packet network and a TDM network. Routing of
the calls from the PSTN to a SIP service node (e.g., call center) is performed by the Mediant
2000/SIP internal routing feature or by a SIP Proxy.
Both of the above applications are depicted in Figure 1-3 on page 12.

Mediant 2000/SIP User’s Manual 2. Hardware Installation
Version 4.2 Beta 15 June 2003
2 Hardware Installation
2.1 Hardware Installation Procedure
2.1.1 General
The Mediant 2000/SIP Gateway comprises a single AudioCodes CompactPCI™ board and a 19-
inch 1U chassis with 110/220 VAC or optional 48 VDC power supply. The cPCI board is a high-
density, hot-swappable, compactPCI resource board with a capacity of up to 480 ports,
supporting all necessary functions for voice, data and fax streaming over IP networks.
This board is available with a rear I/O configuration in which both PSTN trunks and Ethernet
interface are located on a passive rear I/O module.
Figure 2-1: Mediant 2000/SIP Gateway Front View
2.1.2 Available Configurations
The Mediant 2000/SIP is composed of two identical Media Gateways: Gateway-1 and Gateway-
2, each containing 240 DSP channels. These Media Gateways are fully independent, each
Gateway having its own MAC and IP addresses, its own LAN interface and LED indicators. Two
10/100 Base-T Ethernet connectors are provided on the Gateway rear panel, these LAN
interfaces being connected to Media Gateways via an internal LAN switch.
The Mediant 2000/SIP Gateway is provided in the following configurations:
E1 Available Configurations:
" 30 Channels on 1 E1 span with Gateway-1 only
" 60 Channels on 2 E1 spans with Gateway-1 only
" 120 Channels on 4 E1 spans with Gateway-1 only
" 240 Channels on 8 E1 spans with Gateway-1 only

Safety Notice
Installation and service of this device must only be performed by authorized, qualified service personnel.
2.1.5 Installation
$ To install the Mediant 2000, take the next 5 steps:
Step 1 Insert the Mediant 2000/SIP into the 19-inch rack and fasten the left-hand and right-
hand brackets to the vertical tracks of the 19-inch rack, using standard 19-inch rack
bolts (not provided). Now read Note 1 below.
Note 1: When using 100/240 VAC power supply continue with Step 2. When using the optional DC
power supply continue with Step 3.
Step 2 Using 100/240 VAC power supply
Attach a certified 100/240 VAC power cable to the rear AC socket and connect to the
correct AC power supply.
Now read Note 2 below.
Step 3 Using the optional DC power supply
When the optional DC power supply is used, the Gateway is equipped with a DC
power inlet (type MSTB2.5/2-STF of Phoenix Contact). Use #14-16 AWG cables for
the DC connection. The DC input is floating and the maximum input current is 4 amp.
Now read Note 2 below.
Note 2: When using the Mediant 2000/SIP E1/T1 Gateway with 50-pin Telco connectors continue with
Step 4.
When using the Mediant 2000/SIP E1/T1 Gateway with RJ-48c connectors continue with Step
5.
Step 4 Using 50-pin Telco Connectors for Trunk I/O.
Connect the E1/T1 cables to the Mediant 2000/SIP Gateway E1/T1 interfaces on the
rear I/O panel. These are two 50-pin female Telco connectors (DDK 57AE-40500-
21D) labeled Trunks 1-8 and Trunks 9-16 on the rear I/O module shown in Figure 2-3
on page 16, and detailed in Figure 2-4 on page 18. The pinout of the 50-pin
connectors is shown in Table 2-1 on page 18.
Now read Note 3 and continue with Step 6.
Note 3: The User’s 50-pin male connector of Trunks 1 to 8 is connected to the 50-pin female
connector labeled E1/T1 1 to 8. The User’s 50-pin male connector of Trunks 9 to 16 is
connected to the 50-pin female connector labeled E1/T1 9 to 16. These 2 male connectors
must be wired identically, according to Table 2-1and Figure 2-4, both shown below.

Step 5 Using RJ-48c Connectors for Trunk I/O
Connect the E1/T1 cables to the Mediant 2000/SIP E1/T1 interfaces on the rear I/O
panel. These are eight RJ-48c connectors labeled Trunks 1 to 8 on the rear I/O
module shown in Figure 2-9 on page 23. The RJ-48c connectors are wired according
to Figure 2-5 shown on page 18.
Now continue with Step 6.
Step 6 Connect Category 5, LAN cable to the Ethernet 1, and optionally Ethernet 2, interfaces
(RJ-45) on the rear I/O module (shown in Figure 2-3) to your IP network.
For redundant operation, connect Ethernet 1 to Ethernet Switch #1 and Ethernet 2 to
Ethernet Switch #2.
The RJ-45 connectors labeled Ethernet 1 and Ethernet 2 are wired according to
Figure 2-5 shown below.

2.1.6 Board Replacement
" The Mediant 2000/SIP cPCI board, which is also the TP-1610 cPCI board, is hot-swappable,
meaning that the board can be inserted and removed when the Mediant 2000/SIP chassis is
under power.

Mediant 2000/SIP User’s Manual 2. Hardware Installation
Version 4.2 Beta 19 June 2003
" When removing the cPCI board from the cPCI chassis, press the two red latches and wait for
the blue LED to light, indicating that the board can be removed.
" When inserting the cPCI board into the cPCI chassis, press the two red latches and insert
the board. Wait for the blue LED to light, indicating that the board has been inserted
correctly.
2.1.7 Optional CPU Board
The Mediant 2000/SIP provides an optional second cPCI slot that can be used for Customer’s
CPU board. This CPU board can be used for general applications such as SIP Proxy, Softswitch,
Application Server or other. The following CPU boards were tested for compliancy with the
Mediant 2000/SIP chassis:
" Sun™: CP2080 + PMC-233 (Ramix™ disk on board).
" Motorola™: CPV5375-700-02 (with integral HDD) + CPTM-01 (RTM).
