Acme Packet 3900 Physical Interfaces - Oracle Netra Server X5-2 Installation Manual

• INT—The system uses this 10/100 Mbps port for signaling and media traffic that is
outbound with respect to the Remote Office/Branch Office (ROBO). This traffic originates
from the ROBO.
• EXT—The system uses this 10/100 Mbps port for signaling and media traffic that is
inbound with respect to the Remote Office/Branch Office (ROBO). This traffic is being
sent to the ROBO.
• UNUSED—This port is not currently operational.
The graphic also displays the T1/E1 NIU installed above the data interfaces. The T1/E1
interface supports an RJ48C connecter using Shielded Twisted Pair cable.
The Acme Packet 1100 can be shipped pre-configured for basic operation. From a physical
perspective, the INT and EXT ports are the same, but the configuration pre-defines a number
of complex ACLI configurations that make the INT suitable for cabling to internal ROBO
infrastructure and the EXT suitable for cabling to infrastructure external to the ROBO.
The table below lists the labeling of each interface on the NIU, as well as the applicable
operation-type and port parameters in the phy-interface configuration element. Note that
the slot parameter for network management ports is always zero (0). The operation-type
parameter distinguishes between otherwise overlapping slot/port configuration.

Acme Packet 3900 Physical Interfaces

The Acme Packet 3900 platform uses one Network Interface Unit (NIU) that contains all
external interfaces with ports for T1 and E1, serial management, network management,
USBs, and media management.
The following illustration shows the NIU labels and ports, which you need to know about
when you perform the phy-interface configuration.
