We categorize Cisco TAC inquiries according to urgency:

• Priori ty level 4 (P4) —You need information or assistance concerning Cisco product capabilities,

product installation, or basic product configuration.

• Priori ty level 3 (P3) —Your network pe rformance is degraded. Network functionality is noticeably

impaired, but most busine ss operations continue.

• Priori ty level 2 (P2) —Your production network is severely degraded, affe cting significant aspects

of business operations. No workaround is available.

• Priority level 1 (P1)—Your product ion n et w ork is d ow n, a nd a c rit ica l im pac t to bus ine ss op erat io ns

will occur if service is not restored quickly. No workaround is available.

The PA-VXAs are single-width port adapters with one universal port that is configurable for either a T1 or E1 connection. Using a PA-VXA packet voice port adapter, Cisco 7200 series routers, Cisco 7200 VXR rout er s, a nd C isco 75 0 0 se ri es r o u ter s c an become ded i cat ed p acke t vo ic e h ub s o r p ack et voic e gateways that connect to both private branch exchanges (PBXs) and the Publ ic Switched Telephone Network ( PS TN ) .

The PA -VX B and the PA-VXC (see Figure 1-3 and Figure 1-4) are mu lt ich annel packet voice port adapters that allow Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco 7301 routers, Cisco 7401ASR routers, and Cisco 7500 series routers to become dedicated packet voice hubs or packet voice gateways th at co nn ec t t o bo th p r ivate bra nc h exch an ge s ( PBX s ) and the P ubli c S w i tc hed Telephone Network ( P S TN). Wit h this technology, packet voice and packet fax ca lls can be placed over the wide-area network (WAN) and sent through the gateway into the traditional circuit-switched voice infras tr ucture .

The PA-VXB and P A-VXC are single-width port adapters with two universal ports that are configurable for either T1 or E1 connections. The PA-VXB contains 12 high-performance digital signal processors (DSPs) that support up to 48 medium-complexity or 24 high-c om plexity channels of compressed voice. The PA-VXC contains 30 high-performance DSPs that support up to 120 medium-complexity or 60 high-complexity channels of c ompressed voice.

In Voice over IP , the DSP segments the voice signal into frames, which are then coupled in groups of two and store d in voice packets. These voice p ackets are t ra nsp o rt ed u sin g IP in co m p li an ce wi th I TU - T specification H.323. Because Voice over IP is a delay-sensitive application, you must have a well-engineered end-to-end network to use it successfully. Fine-tuning your network to adequate ly

The PA-VXA, PA-VXB, and PA-VXC have the following features:

• Universal ports—One interface port (PA-VXA) or two interface ports (PA-VXB and PA-VXC) per

port ada pt er ar e configur ab le as either T 1 ( w it h in teg ra ted C S U/D S U ) o r E1 (with in teg ra te d G.703/G.704 120-ohm interface). Additionally, a port may be configured on a per-DS0 basis for voice termination, time-division multiplexing (TDM) pass-through (cross-connect), or packet data.

• High-density digital signal processor (DSP) technology—Full s up p or t exi s ts f o r low - bi t- r ate voice

sending data when no voice is present. Comfort-noise generation prevents uncomfortable dead silence on the re ceiving end .

• Multiple clocki ng options—Ports can be clocked internally from the network, or the network cl ock

from one port can be sent to the other port on the card or to other cards across the MIX bus in the VXR chassis.
