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.

Ports key
- T1/E1—For Time Division Multiplexing (TDM) quad span
- SER MGT—For console access for administrative and maintenance purposes
- MGMT0—For EMS control, RADIUS accounting, CLI management, SNMP queries and traps, and other network management functions
- MGMT1 and MGMT2—For High Availability (HA), or for network management with no HA configuration
- USB—For a storage device, or for installing software
- P0 - P3—For signaling and media traffic on copper or fiber optic cable
When performing the phy-interface configuration, refer to the following table for mapping each NIU label and operation-type to the appropriate slot and port parameters.
| NIU Label | Operation-type | Slot | Port |
|---|---|---|---|
| Mgmt 0 | Maintenance | 0 | 0 |
| Mgmt 1 | Maintenance | 0 | 1 |
| Mgmt 2 | Maintenance | 0 | 2 |
| P0 | Media | 0 | 0 |
| P1 | Media | 0 | 1 |
| P2 | Media | 1 | 0 |
| P3 | Media | 1 | 1 |
