Dynamips和Vmware完成CCVP试验(2)

2009/02/25
更换所有IOS为c3745-ipvoice_ivs-mz.124-2.T6，此IOS支持GK/GW/CME特性，而且可以添加4个以太网口
PSTN GW绑定到VMnet1, 在宿主机上安装CIPC7.0(原来的低版本CIPC有问题，不能显示号码)；而用VTGO一条line上不能显示多个号码
CME设置：无需load 7960 firmware;无需cme-basic-4.0.0.0升级包，直接依照向导设置即可使用

TIP:安装DNA(CCM上的号码分析工具)时不要运行CCM管理界面，同时关闭CIPC

HQ-->PSTN通了，原来CCM上RL指向有误，应该指向GW，但是指向了host vmnet1,更改指向，添加RP，单通了

PSTN-->HQ不通，HQ上出现如下错误提示：
*Mar  1 00:44:14.475: %CALL_CONTROL-6-CALL_LOOP: The incoming call has a global
identfier already present in the list of currently handled calls. It is being re
fused.
cisco官方解释：
%CALL_CONTROL-6-CALL_LOOP : The incoming call has a global identfier already present in the list of currently handled calls. It is being refused.\n

Explanation    The incoming call has a global identifier that is already present in the list of currently handled calls. A global identifier can be used by .ly .e call at a time.

Recommended Action    Check your configuration. The call may be misdirected.

1.尝试更改CCM上的Route Pattern，失败
2.尝试改用硬件搭设voice lab，2800系列太贵，2600不容易凑齐模块，1750也凑不齐模块，只好放弃
3.关于cisco voice module和voice card的一些说明
2600/1700系列上语音卡需要carrier module，如NM-1V（NM-HD-2VE）
NM-1V(NM-2V)只能用VIC开头的卡：
VIC-2FXS
VIC-2FXO

NM-HD-2VE只能用VIC2开头的卡：
VIC2-2FXS
VIC2-2FXO

两者不能通用(interchangable),切记！！！

VWIC指既可以做数据E1，也可以做语音E1
VWIC-1MFT-E1 语音E1
VWIC-1MFT-G703 数据E1

For the NM-HD-1V, NM-HD-2V, and NM-DS-2VE network modules, DSPs are .-board and are not field-replaceable units (FRUs).

PVDM and PVDM2 modules are not interchangeable. Use PVDM modules with the NM-HDV network module .ly, and use PVDM2 modules with the NM-HDV2 network module .ly.

?NM-HDV2, with no built-in T1/E1 ports

?NM-HDV2-1T1/E1, with .e built-in T1/E1 port

?NM-HDV2-2T1/E1, with two built-in T1/E1 ports

PVDM Versus PVDM2
PVDM:单任务处理，静态分配资源，要么voice termination，要么transcoding，要么conference bridge resources；NM-HDV---->C549 DSP---->PVDM-12

PVDM2:多任务处理，可以同时voice termination, transcoding, and conferencing simultaneously.
NM-HDV2/NM-HD-XX---->C5510 DSP---->PVDM2-X(8/16/32/48/64)

The remainder of this section focuses . the capabilities of the PVDM and PVDM2. The PVDM utilizes the C549 DSP and is available . the NM-HDV series of network modules. .ly .e model of PVDM exists, and it is equipped with three C549 DSPs. The actual part number is the PVDM-12. The -12 indicates that the PVDM can terminate a maximum of 12 voice callsfour calls . each of the C549 DSPs.

The PVDM2 utilizes the C5510 DSP and is available in the NM-HDV2 series of network modules and the Intermediate Session Routing (ISR) family of routers. The newer DSP that is used in the PVDM2 allows for higher-density voice termination and increased transcoding and conferencing sessions. Five models of the PVDM2 exist, as shown in Table 14-1, each equipped with a different number of DSPs. As with the PVDM-12, the xx in the PVDM2 part number indicates the maximum number of voice channels that the PVDM2 can terminate.

The C549 DSPs are dedicated to .e task. When you use PVDMs, the DSPs are statically assigned to voice termination when the router is started, or in the case of T1 and E1 ports, when the voice port is created. If additional DSPs are available, you can configure them to provide transcoding or conference bridge resources.

C5510 DSP allocation is more complex. For analog and BRI ports, C5510 DSPs are statically assigned to voice termination when the router is started. C5510 DSPs are dynamically assigned to provide voice port termination for T1 and E1 ports and for transcoding. A single C5510 DSP can provide both functions simultaneously. Conferencing is still statically defined, and a C5510 DSP that is configured as a conferencing resource cannot serve any other function.
