Cabletron Systems CSMIM-T1 Manual De Usuario

Using Bypass Mode will allow a connection to the network to be 
maintained even though the system is powered down (or not on-line). If 
all channels are not being used for modem applications, the DSX1 
interface could be used to drop-and-insert the PBX voice channels into 
the DS1 connection. (In this example, it requires that the PBX have an 
integral T1-CSU to terminate the network.)

When installing the CSMIM-T1, keep the following in mind:

You may install the CSMIM-T1 in any slot except for slot 1 (farthest 
slot to the right) of the MMAC chassis.

We suggest positioning the CSMIM-T1 next to any contiguous RIC 
MIMs or MIMs directly controlled by the hub managing device (e.g., 
EMME, EMM-E6, etc.). This does not apply to shunting 
MMAC-FNBs, where the data path remains unbroken, and allows 
non-interrupted communication.

Install the CSMIM-T1 into the MMAC-FNB (backplane) as follows:

In addition to J12 and J24, there are other jumpers on the 
module. These are used for diagnostic purposes, or are factory 
presets. Changing any of the jumper positions could cause 
damage to your module.

Installation should be performed by qualified personnel only.

The CSMIM-T1 is sensitive to static discharge. Follow static 
safety handling rules and properly wear an antistatic wrist 
strap.

Although Cabletron Systems modules have “hot swap” 
capabilities, we recommend that you power down the MMAC 
hub prior to installation.
