The PA-MCX has the following features:

• Universal ports—Two, four, or eight interface ports per port adapter are configurable as either T1 (with integrated CSU/

DSU) or E1 (with integrated G.703/G.704 120-ohm interface). Additionally, a port may be configured on a per-DS0 basis

for voice termination, TDM pass-through (cross-connect), or data.

• MIX support—Voice channels can be time-division multiplexing (TDM) switched between port-adapter slots in the Cisco

7200 VXR chassis. This allows DSP resources to be shared between port adapters in the same chassis or for port-to-port

DS0 cross-connect between port-adapter slots.

• DS0 drop and insert—Flexible TDM cross-connect capability between ports and the MIX bus is available.

• Multiple clocking options—Ports can be clocked internally from the network, or the network clock from one port can be

sent to the other port on the card or to other cards across the MIX bus in the Cisco 7200 VXR chassis.

The following enhanced voice features are supported when the MIX-enabled T1/E1 port adapters are used in combination

with the enhanced digital voice port adapter (PA-VXC-2TE1+, PA-VXB-2TE1+):

• Voice-over-IP (VoIP) and Voice-over-Frame Relay (VoFR) termination

• Full-featured DSP firmware—

Support for several standard-compression algorithms (G.711, G.729a/ab, G.723.1, G.726, G.728)

Echo cancellation

Full dual-tone-multifrequency (DTMF)/MF tone detection and generation, and dial pulse generation.

• Silence suppression

• Flexible signaling support—Channel-associated-signaling (CAS) and common-channel-signaling (CCS) support is available

for both E1 and T1 applications.

• T1 CAS (robbed-bit signaling)

• E1 CAS—R2

• PRI (user and network side)

• Transparent CCS

• Q.SIG

• FG-D

• Multi-D channel

• Simple Network Management Protocol (SNMP) compliant

• Manageable via a Management Information Base (MIB) browser

• CiscoView interface for configuration

• Cisco Voice Manager (CVM) supported

• Netsys supported

• Approved in most countries

• Software-configurable ring-cadence and call-progress tones
