For data applications that require T1 CSU and DSU

functionality, the two-, four-, and eight-port MIX-enabled

T1 port adapters provide the right mix of integration and

cost. For E1 applications, the MIX-enabled E1/G.703

interface allows direct connectivity to 120-ohm

G.703 lines.

The 128 channels of the MIX-enabled port adapter can be

allocated among fractional T1/E1 links, N x DS0 (N x

64K) links, or ISDN Primary Rate Interface (PRI) links.

For each N x DS0 (N x 64K) connection, a single

channel is consumed and multiple N x DS0 connections

can be supported on a single T1 or E1. Each T1 or E1

used as ISDN PRI consumes either 24 or 31 channels,

respectively, one for each B channel and one for the D

channel. A total of 30 ISDN PRIs can be supported on a

Cisco 7206 VXR series router on a T1 link, and 24 ISDN

PRIs can be supported on an E1 link.

Features

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 an 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 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 crossconnect 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.
