- Per-port rate shaping on output
- Packet buffering, Layer 2 parsing
|
Software features | - DS3 functionality:
- C-bit framing
- B3ZS line encoding
- DS3 diagnostics and loopback control
- DS3 alarm and event counting and detection
- Per-packet counts and byte counts
- Local and remote loopback testing, as well as BERT testing
per DS3
- DS3 far-end alarm and control (FEAC) channel support
- Encapsulations:

|
Cables and connectors | - Custom 10 ft (3.05 m) posilock SMB to BNC male cable,
separate Rx and Tx (provided)
|
LEDs | One tricolor per port: - Off—Not enabled
- Green—Online with no alarms or failures
- Yellow—Online with alarms for remote failures
- Red—Active with a local alarm; router has detected
a failure
|
Alarms, errors, and events | - Alarm indication signal (AIS)
- Bit error rate test (BERT) functionality on PIC (you can
configure one DS3 channel in BERT mode and configure the remaining
channels to transmit and receive normal traffic)
- Equipment failure (does not affect service)
- Far-end block error (FEBE)
- Frame error
- Idle code, Idle received
- Local and remote loopback
- Loss of signal (LOS)
- Out of frame (OOF)
- Parity bit (P-bit) disagreements
- Path parity error
- Yellow alarm bit (X-bit) disagreements
