CHAPTER5 Cabling the Device Mediant 500L Gateway & E-SBC | Hardware Installation Manual
5 Cabling the Device
This chapter describes the cabling of the device.
Connecting LAN Interfaces
The device's Gigabit Ethernet LAN ports (1000Base-T) can be connected to network equipment
and entities such as computers, switches, and IP phones. These ports support half- and full-duplex
modes, auto-negotiation, and straight or crossover cable detection.
The Ethernet ports can operate in pairs (Ethernet Groups) to provide 1+1 port redundancy, where
one port serves as the active port while the other as standby. When the active port fails, the device
switches to the standby port. By default, the Ethernet ports are grouped into pairs, as shown in the
following figure with the port string names used for software configuration. You can change this port
assignment, including assigning only a single port to an Ethernet Group. For more information, refer
to the User's Manual.
Figure 5-1: Default Ethernet Port Groups and Port String Names for Software Configuration
The Ethernet cabling specifications include the following:
■Cable: Straight-through, Category (Cat) 5e cable
■Connector: Standard RJ-45
■Connector Pinouts:

1. Connect one end of a straight-through RJ-45 Cat 5e or Cat 6 cable to the LAN port, located on
the rear panel and labeled GE LAN.
Figure 5-2: Cabling LAN Ports
2. Connect the other end of the cable to a network device or entity.
3. For 1+1 LAN protection, repeat steps 1 and 2 for the standby port, but connect it to another
network (but in the same subnet).
Ethernet port interface cabling must be routed only indoors and must not exit the
building.
ISDN BRI Interfaces
This section describes how to connect the device to ISDN BRI lines.
Connecting BRI Lines
The BRI ports can be connected to ISDN terminal equipment such as ISDN telephones or PBXs.
Each BRI port can be configured either as termination equipment/user side (TE) or network
termination / network side (NT). Up to eight terminal equipment (TE) devices can be connected per
BRI S/T port, using an ISDN S-bus providing eight ISDN ports. When configured as NT, the BRI
port drives a nominal voltage of 38V with limited current supply of up to 100 mA.
To protect against electrical shock and fire, use a 26 AWG min wire to connect the BRI
ports to the PSTN.
- 13 -

CHAPTER5 Cabling the Device Mediant 500L Gateway & E-SBC | Hardware Installation Manual
BRI interface is a separate orderable item which is supported only on specific hardware
configurations. For more information, contact your AudioCodes sales representative.
The BRI cabling specifications include the following:
■Cable: Straight-through, Category (Cat) 5, 5e or 6
■Connector: Standard RJ-45
■Connector Pinouts:
Figure 5-3: RJ-45 Connector Pinouts for TE or NT BRI Ports
➢To connect a BRI line:
1. Connect the RJ-45 cable to the device's BRI port, located on the rear panel and labeled BRI.
Figure 5-4: Cabling BRI Ports
2. Connect the other end of the cable to your ISDN equipment.
Connecting PSTN Fallback for BRI Lines
The device supports PSTN Fallback for BRI lines. If the device loses power, for example, due to a
power outage or the unplugging of its power cable, it automatically routes calls from the Tel side to
the PSTN (instead of the IP network). This guarantees call continuity.
The BRI PSTN Fallback uses BRI ports #1 and #2. When the BRI PSTN Fallback is activated, the
internal metallic relay switch of BRI port #1 automatically connects BRI ports #1 and #2, and calls
can be routed and established between these entities.
- 14 -

CHAPTER5 Cabling the Device Mediant 500L Gateway & E-SBC | Hardware Installation Manual
➢To cable the BRI PSTN Fallback:
1. Connect BRI line 1 (Port #1), located on the rear panel, to an ISDN PBX.

Figure 5-5: Cabling BRI PSTN Fallback
●For the four-BRI port configuration, fallback is not supported on ports #3 and #4.
●The BRI PSTN Fallback feature is a separate orderable item, which is supported
only on specific hardware configurations providing BRI interfaces. For more
information, contact your AudioCodes sales representative.
●The BRI PSTN Fallback feature has no relation to the PSTN Fallback Software
License Key.
Analog Interfaces
This section describes how to connect the device to analog equipment.
Connecting FXS Interfaces
The procedure below describes how to cable the device's FXS interfaces.
●The device is an INDOOR unit and therefore, must be installed only indoors.
●FXS port interface cabling must be routed only indoors and must not exit the
building.
●Make sure that the FXS ports are connected to the appropriate, external devices;
otherwise, damage to the device may occur.
●FXS ports are considered TNV-2.
